I purchased a salvage vehicle. The engine ran perfect but auto transmission was bad. I took the engine out of the salvage vehicle and installed it in my vehicle( manual Trans). Connected everything up vehicle cranks over but will not start. Act like it about to start but won't. Replaced the fuel pump, 3 distributors( rebuilt from auto zone), fuel filter, changed ECU, hear fuel pump humming when starting, jumped fuel pump for a data connector. There appears to be an electrical pump somewhere in the vehicle but I can not find it. The engine work well in the salvage vehicle. When I installed it in my vehicle I went back to the initial problem. No start.

Got spark at the plugs? Will it run on carb cleaner sprayed into intake plenum?

Yes, I have spark. It will hit/ run a little by spraying starting fluid through the throttle body. I also sprayed gasoline in the throttle body and it only hit/run a second. I checked for current at the injectors and there is. In my initial send help message, I meant to say there appears to be an electrical problem not electrical pump. I have probe wires to make sure there were no breakage or short. Like I mentioned the engine ran great in the salvage vehicle but when I installed it in my vehicle, the same problem remained. I even replaced the fuel tank. The ECM was not used from the salvage vehicle because of the transmission and it was different than the manual.

Fuel pressure needs to be checked!
ReplyCG3wd, October 24, 2013, 06:25Rookie
When I checked the pressure while cranking I had 30 psi but most manuals states checking while engine is running. I even checked by jumping at data connector. Had the same. Are these false readings? If it won't start, what other means can I check it?

I have talked to mechanics as I hope I am here. All thinks it may be fuel management or electrical issues, which I have tried their suggestions. The distributor have the built in coil and crank position sensor. It has a lifetime warranty which is why it has been changed three times. I have not been able to find any shop that can bench test them.

there are other tests that can be done if the vehicle is present at a shop
