Got fuel and spark, does not fire up

[SuperchargedSHOguy]

Okay, some updates. I checked the timing of the engine TDC with cam sensor off and it was identical another SHO so I know the engine timing is 100%. I had one injector o ring leaked so I replaced that along with the return fitting on the fuel rail whick also had a leak from getting knicked.. I also put in some autolight 3923 plugs gapped at about 40 tonight (I like the results and run them on all my SHOs). Unfortunatly it did not start but for some reason there is no pulse to the injectors so I will look at those tomorrow and maybe it may start.

check the intake manifold gaskets? Had the same problem changed them and fire right up

gaskets are in great condition. It may fire up, I've verified and changed a few things the last 2 days and it could run...don't know till tomorrow.

Hmmm, something isn't right for sure .....

Are you sure you have all the connections connected(and correctly)? Mainly under the throttle body, and behind the engine by the rear manifold....

 

[SuperchargedSHOguy]

All the connectors are connected. Had a few of the other FSHOC guys look at it yeaterday. Not sure why no pulse now because we had it before- gonna look at the ECU again later once I do a tune up on my Cav.

Other food for thought on the fly:

-Ground between the fuel rails , next to the knock sensor.

 

[SASHO91]

Isn't that for the O2's though?

Im actually not sure what this ground is for. If my memory doesnt play tricks on me , I think I saw a no-start with that ground un-hooked.

Yes, that is the 02 ground.

Don't know for sure if this is the situation, but a 1/2 way seated LPM or TwEECer will give you a "no start".

 

[SuperchargedSHOguy]

That ground on the block is hooked up. No chip or tweecer either. I put in a different ECU today and still had no fuel. Also ran codes- 52 85 87. Still have fuel at the rails. Ran out of time to go any further, I'll get back on it Monday.

Also, these codes were pulled while I had a l0s ecu installed, not the x2j.
