Got a 89 with the 2.8 MFI engine from my brother-in-law that had broken a rod and threw the pieces through the side of the block. Got a RECON to replace it and worked over the summer with my son to install it. We've got it in, but the thing won't start. Took me a few hours yesterday to get the spark sparking - turned out to be faulty connections at both the crank sensor and the ICM. Now, plenty of spark but no fuel - pulled a couple of plugs after cranking on it long enough to wear a new battery down and they are as dry as the Sahara.

Took the plenum off and plugged noid lights into the injector harness. They flicker merrily along. Tested pressure at the fuel rail and it cycles up to 40 psi after turning on the key, drops back to zero shortly after turning off the key.

I've read a lot of posts that suggest pulling the fuel rail and looking at the injectors, but I'm hard pressed to believe all 6 injectors would clog simultaneously, but stranger things have happened. The only thing that gives that theory credence is I did pull the intake manifold off the old engine several months (like 8) before putting it on the new one. Maybe that gubered up all 6 injectors, but I'm doubtful.

No codes out of the ECM - I don't even think its involved yet as I thought it didn't do anything until the engine RPM reached over 400. Most of the scan tools I've seen start out.....with the engine at idle...which I where I'm trying to get to!

I read a post somewhere that seemed to think the EGR valve could cause this type of problem. Is that worthwhile looking into - its easier to remove and clean that then the injectors.

I'll probably spend the day looking at the EGR valve - I had planned to test all the sensors, TPS, IAC, MAT and so on, but if the noid lights are a flickering, seems all those are at least within tolerance, no?

Any suggestions you've got are welcome, even ones that you think I had already looked at - I could miss something trivial. I did check all the ground wires and such - keep going back to the noid lights wouldn't work at all if those were faulty.

Thanks in advance,

Greg
