that is what i am thinking also,that is where i am going to start,maybe tomorrow,can't work on it today,other obligations.

 

You ever figure this out?

 

no,replaced cap and rotor today,still not enough spark,I borrowed a noid light,going to check and see if the injectors are firing,if those prove out ok,then I guess I will replace the dizzy,not real sure what else to do right now.

 

well,just did the noid light test,injectors are firing,so not really sure what is going on now,the spark is blue now since I replaced the dist cap and rotor,really at a loss at what to do next.

 

Don't really mean to nose in this late in the game...

As someone, and maybe the Poster did mention about the PIP, could the PCM not receive the PIP, and not fire the engine over? If you didn't have PIP, would you still have spark? I'm unsure, that's why I am asking too. If there is blue spark, could something else have gone awry in the time that has elasped since the beginning of the Post. Perhaps the neutral saftey switch is now causing problems? Would you have spark if the saftey switch was going bad? I'm just as curious about this problem and I hope with all our suggestions and ideas, hopefully somewhere down the road, his problem will get resolved.

 

those are good questions,timbersteel. I am really starting to suspect internal engine failure,going to do a compression check tomorrow,then pull the dizzy and replace it with one a friend snuck out of a local parts store so i don't have to pay for it,to see if that is the problem,then I will buy it.

 

I would throw in a new set of Autolite or Motorcraft spark plugs while you got them out doing a compression test. I would also get a can of starting fluid to help it out.

 

plugs are cheap and it has been a couple years,wouldn't hurt to replace them.

 

I had originally written a reply concerning replacing the plugs, erased it, since another member posted it that before, but did not know that you hadn't since having all the issues. I would definately try that Cjben. That and with help from you local parts house friend, perhaps trying a diff. dizzy may help as well!

Good Luck! Will definately be around to see your progresss!

 

I would say that if the injectors are firing then the pip is doing something. When you change out the plugs id turn it over by the starter relay to clear any extra fuel from the motor. I would double check the rotor position on #1 compression stroke to verify that the timing chain didnt jump.

 

Neutral safety switches only interrupt the starting circuit, they do not affect spark or timing in any way, also activates back-up lamps.

 

Well,Bad news on the compression test,numbers are very low. I am not sure if they are low enough to not have enough compression to start the engine,but they do tell me to start shopping for a new/used engine. Here they are:
FRONT OF ENGINE
1)110 5)70
2)90 6)95
3)100 7)65
4couldn't get the 8)85
tester hooked up
because of the firewall

tomorrow I am going to go ahead and put new plugs in and see if she will start,but my days of being a ford truck owner are most likely numbered. I do not have money for a new truck,can't get the truck in the garage when it's not running,and really don't have time to do an engine swap myself. sad day for me

 

Timing chain!!!!!!!!!!!!!!!!!!!! I almost bet that with new plugs it may start but It probably wont run for crap. You could try advancing the wires on the cap one terminal to see if it may start. I actually had this same problem a few years back,double and triple checked the timing at tdc and rotor. Seemed ok but with starting up with new plugs and the wires moved i didnt have to push it in the garage but it only went 2 ft at a time. Even with the new chain the truck was very hard to start,due to the amounts of fuel in the engine. I actually had half of the teeth gone but not at tdc so i didnt see a lot of movement in the chain by turning the pulley. I was ready to change out the engine so i pulled the timing cover and found my problem pretty fast.

 

First of all, sorry for your loss, hope it's not true and is something easier like t chain or gears. or better yet, a mouse / mud bees nest blocking the intake. or collapsed exhaust/coverter.

Did it ever run? Is it new to you?
what/how long did it take to go bad?

 

if it were the timinmg chain,wouldn't there be slack in it when I turned the motor backwards? I turned the motor backwards and watched the rotor,there wasn't a bit of slack. I do agree,it may be the timing chain because it did this all of a sudden,it was running GREAT before it died. Is there another way to check and see if it is the timing chain? Like i posted before,timing marks are dead on.

I have had the truck 3 years,was running GREAT before it died suddenly a month ago.
