swapped my 5.8 motor now it will not run.. been stranded for 4 days it turns over but will not start. checked wiring even took brain out of other truck. still nothing anyone near seaford willing to help!!

 

So it was running? If so what happened did it just shutoff(ignition) of sputter and stumble(fuel)?
Have you checked fuel pressure?
Is there any spark?

 

checked fuel has fuel coming out while starting. when you spray starter fluid it sputters. motor did run before swap.

 

Maybe a weak coil?

 

Do you get spark?

Double check the firing order and that the wires are on the correct cap pins for each cylinder.

 

Spark? Make sure rotor is at #1 when at TDC. How many miles on motor? Timing chain issue?

 

Fuel coming out of what? You need at least 32psi at the fuel rail for the motor to run.

 

the motor came out of a f-250 it has 612 miles on the motor..... jasper engine....5.8
i parked both trucks next to each other.
i shut off the 250 and immeaditly starting unhooking all hoses and simply unhooked the main harness on the driver wheel well to the motor.unbolted trans and mounts pulled motor out...set it upright on some tires then with engine hoist then got it off the ground.
i repeated this same process on my 350 accept i didnt dissasemble the entire front of the truck like i did the 250.
i dropped the new motor into into my 350 hooked everything up very carefully double a triple checked vac lines wires hoses made sure everthing was correct.
once my 350 was put back together i hooked the battery up and proceeded to start the key sounds realy strong but wont run.........when spraying starting fluid(carb choke cleaner only thing available) it springs to life but only enough for the fluid to burn out which is maybe 3-5 seconds unless i keep a mist spraying it will go until it runs out.......


The things im thinking is maybe the ground isnt tight enouph. but i bolted on another ground wire to the block same results.
and this morning comparing the 2 motors to make sure i didnt forget anything i noticed my harmonic balancer i assume thats what its call front of block bottom . is fine on my 5.8 and then looking at the new motor it is not on the left side as is on the old motor it looks to be on the right side... and also it looks bent but it started pouring and ive been sleeping and working on my truck since saturday.........i also took the brain from 250 and put it in mine same results.....
so if the ballancer is bent away from the front of motor will it not run and what exactly is its purpose.....

 

It sounds like a fuel delivery problem. Can you check fuel pressure?

 

not the balancer itself but the think bolted next to it

 

i m broke as of right now so cant buy any special toold or anything......i did notice the larger fuel line on the 350 looks like it got hung up the rubber is a bit cut but nothing leaking if it were to have gotten pinched would it stay pinched? it should atleast start witht he amount of fuel comming out of the rail it shoots up around -5 inches when cranking.....

 

2-5 inches**

 

I haven't done this before, but I believe a tire pressure gauge will fit on the fuel pressure schrader valve. You could maybe use a tire pressure gauge to get a rough estimate of fuel pressure.

 

some pics of the motor swap and the apitimy of backyard mechanic

 

No bueno on this idea...

Can squirt fuel everywhere, and cause some harm to you.
