1994 dodge ram no spark no fuel pump.
#21
Well heres the update. I tested the coil and i seem to have power going to it. And leaving it. It wont light up a test light. But i see in on the voltmeter. Fuel pump kicks on for three seconds. Shuts off. Fuel pump stays running when cranking. Pulled the distributer after putting it on tdc. Checked all plug eores. Still nothing. Tried jumpimg pin 30 and 87. No visual spark on the spark tester. Check engine codes are 11 12 24 37 45. The pcm is still making a high pitch noise. Cleaned all the grounds i could find. Still nothing

Ok, so, the pcm seems to be doing everything it should, except fire the coil...... Check the control circuit for the PCM for continuity from coil to PCM.
11 No crank reference signal at PCM. <- That's not good.
12 battery disconnected <- not a big surprise to see that one.
24 throttle position sensor voltage out of range.
37 TCC circuit, or trans temp. <- do you have a temp sensor on your trans? It would be on the cooler line coming out of the front of the trans.
45 O/D solenoid circuit failure.
Verify you are getting 5 volts to the TPS, and crank sensor. A lack of reference voltage would most certainly cause some trouble.
The pcm *seems* to be seeing the engine turning...... even though you are getting a ckps code..... wonder if it is just going by the cam position sensor......

Did it come from the factory with the manual trans? If so, has the pcm been changed to your knowledge previously? Several of those codes are auto-trans specific, and you should NOT be seeing them.
Wonder if you are getting injector pulse? Do the plugs get wet? Do you smell gas out the exhaust at all? Might be able to get a noid light to test for injector pulse at the parts store. (either rent, or buy one.)
What brand crank sensor did you get?
