help please help, truck wont start!!!
Ok i bought a 94 single cab ranger with a 2.3l that had a cracked head. I replaced the head with a good one of off a different year 2.3l. It went together well. I installed everything except for radiator, it was time to crank it the motor turned over and over and over.....nothing. I have been pulling my hair out trying to figure out what is wrong. Ive ran through the whole motor over and over, nothing seems to be wrong. I have good spark i have fuel spitting right out the injectors, good fuel pressure, oil pressure, reasonable compression. I checked all my gaskets, no problems see to be there.
The only time i accidentally got it to start is when i was pulling the injectors out to watch them spray, they sprayed into the engine from about a inch away and it started right up. Obviously it just ran wide open cause there was no throttle control. I dont understand why is started this way or if it has anything to do with the problem.
I wonder if it is the computer but i dont know if to replace it. Please someone if you have any ideas please help i need this truck for work and am in desperate need of help. Thanks guys

I have no idea about your truck, but thought I would relate a similar story about my mx6. Could not get it to start. Drove it into work fine, went to leave and no start. I have an exposed timing belt (dont ask), looked good on timing, I had fuel in the cylinders, had spark at the plugs. NOTHING made sense. Turned out it was a fuel pressure regulator on the return. It was stuck so I was flooding it out and would not start. My test for this was to turn the car over for a moment, then disconnect the wires to the injectors (running it without injectors firing) and then try turning it over again with the leftover fuel from just trying it. It would start and try to run for a moment until it burned all the fuel. This test may point you in the right direction if I have interpreted what you wrote right.

Thanks alot MFP, i will try that this afternoon. My truck makes no sense either, i have everything from spark to compression. Did your mx6 have good fuel pressure when your return was stuck? Im actually not too sure if i even have a return regulator i know i have one that is on the fuel rail. Regardless i will run the method you said just to try.
Im kindoff leaning towards the computer being out in it. Im just not sure though. Does anyone know of any good ways of seeing if the comp is out.
Thanks again guys.

Yeah, had too much. I have no idea if it works the same on your truck, but the pump would send fuel at a really high pressure to the fuel rails, after the rails was the pressure regulator valve that would open up and "bleed off" all the pressure above what it was supposed to be and return that fuel to the tank. The regulator got stuck and basically caused the system to over pressurize.
If you have spark and fuel (you know you have that from what you said about the motor chugging when you had the injector spraying down in there) and you have timing you should have everything you need.
but then again, you messed with the head.... what about the head removal and swapping could cause this? Timing should not change right? Not familiar with these motors and throwing things out there. The thing that I keep coming back to is that it tried to start with the injector out. That seems to indicate that even without compression you could get something out of it. Too much fuel for whatever reason is what that points to......

Ive ran over the timing over and over again, its right on. You know, that what i thought too about having everthing. I often felt like it was flooding out too, the only thing i can think about is maybe the computer is sending the wrong signals to the injectors and or the coil packs for the spark plugs. I had a big work truck that had similiar symptons and it turned out to be the computer.
I too wondered if the changing of the head had anything to do with it because the guy i bought it from said it was from a year or to newer but that it was the same head. I checked the cams and they were the same i checked all the holes and everything was the same. The only thing that was different was a mounting hole for the coil packs. I just dont get it, i too think its pointing to the fuel or the timing but i have the timing perfect.
Too anyone who is familiar with the timing and spark plug placement on the coil pack please write in so i can make sure my order and timing is write. Thanks for writing guys, im gonna go check my regulator now to see if i see any problems.

Also back to the computer, i wonder if changing a head may the computer need to be reset. Could it get confused from unplugging just about every sensor on it?
This is stupid but i must try everything, surely its fine to have not have the radiator or ac or power steering hooked up to start it? I know its fine i just must ask.

when you pulled the injector out, it started ti run? well at that exact time, your compression would have dropped and yourair mixture would of changed, intake restriction? also, check your IAT MAF CPS CKS, these can all lead to a no start, try your haynes maunual, that will usually help. gives a good description on no starts.

Well, there are not so many reasons when engine does not start.
1. No PIP
2. No Spak
3. No fuel pressure
4. No power on ECU ore ECU internal fault
5. Mechanical problems, no compression, timing and other....

I have all the necessary mechanical needs for the engine to start. Spark, Timing good, compression, fuel, fuel pressure, oil pressure, i am going to purchase a computer for the car as it is only 100 bucks. I am fairly certain it must be the computer. Theres no other reason for the car to run, even if it was a sensor or so it would still start but would run poorly. I just am getting no kindoff start, so i guess a computer will have to be the test. It should be here in a day or so and i hope this will fix the issue. Does anyone know of any issues they have had with these computers?
Still if anyone has any ideas on what this could be please let me know.

Computer for $100... Better look for ELM327 and software aloving not to scan only but to see actual values and reprogram modules.

Some obd scanners will not work with my truck, and a scanner i bought a few months back did little for me, plus alot that i look at only work for 96 and up vehicles. I purchased a computer for 106.00, i feel firm that this is the problem, if it is not....it must be a sensor issue that i will bring to a reputable source near by and have the codes pulled on the truck...they charge about 65.00 to check on there computers.
Thanks for the tips and if anyone still has any advice please let me know, the comp should be in tommorrow and if this is not the issue and the codes dont show a problem....i just dont know where to go from here.

Yes i sure did MFP, i turned it over for a sec or two, disconnected the injectors, tried again....nothing. I also had a spare pressure regulator of the motor i got the new head from and i replaced it with mine just to make sure it wasnt that. Thanks for the idea i was hoping it was something like that...but i guess ill just have to see with the computer. My father a while ago had a work truck that had this same issue. It had spark fuel etc...everything but just woudlnt start we couldnt figure it out...we changed the computer and it worked ever since...well until the trans wentout. Anyway, ill keep my fingers crossed for an easy fix with the computer. Please let me know if anyone has any other ideas.
