Engine cranks but wont start

[woody7193]

So i got my swap to crank but wont start, the coil doesnt give spark but it worked perfectly fine on my f series , any help?

ECU ground on the t stat housing?

[woody7193]

I connected that wire to a spot on the firewall , does it have to be on the thermostat? It doesnt reach and i dont see a bolt for it

If your coil doesnt give spark NOW, that's kind of your problem. Crank but no start means a fuel or spark issue, and you say yourself you're not getting spark. Check all the wiring related to it. And how does your harness ground stretch all the way to the firewall but not reach the t-stat housing from whence it came?

[woody7193]

Idk it doesnt reach so i just put it by the fuse box , also i dont hear the fuel pump prime so it could be either or , ahh i just miss my car its been a long month

How the hell is that happening? You bolt the ground strap to either the bottom stud where the t stat housing bolts to the intake, or one of the bolts holding the t stat housing together. There should be NO way that ground strap reaches that far.

Idk i have to try something probably go get another coil from the junkyard see if thats it

Can you post a picture of this ground you're referring to so we're sure we're all talking about the same thing?

Ill post them later im at work -_-, so the swap im doing is an h22a , is there a difference?

[CyborgGT]

When swapping in an h22 it's easiest to re-use the f22 harness, adding the new h22 components and swapping the couple connectors that are different, so no there's no difference.

So im dumb , didnt realize that the coil needed ground -_- , so i did that and i got spark, and the car fired up , but the spark is only there for a while and causes the car to turn off so thats where im stuck need to move the wire around to get the spark

[dj_ender]

Sounds like a poor ground.

[woody7193]

Yea but to find it its gunna suck

[dj_ender]

So what about that pic of the ground you said you put on the shock tower or firewall?
