86 2.3l will crank but not fire. I bought this truck from a guy that states "the fuel pump relay went out" replaced the relay and it still wont fire. I have jumped the inertia switch for GP. Here is my current status:
Ignition on: no fuel pump prime. however, 12v power applied directly to the fuel pump relay terminal will turn on the in-tank and HP fuel pump.
I attempted to test the relays (I replaced both the green and brown - fuel and ignition). I applied 12v to the coil and did not hear a click, but I do not know if more modern relays do, or do not have an audible click still. So I then checked the switch side of the relay for continuity while the relay was energized. I did not get continuity. Now I read the wiring diagram a thousand times and looked for a pin out sheet for the relay and I believe I was testing the relay properly, however, I find it odd and unlikely that both new relays could be bad, unless they were fried for some reason upon the first starting attempt, but they are not melted and appear to be good still.moving on.
I also think I am not getting spark ( these could be related problems I think) I removed the number 1 spark plug and the boot and cracked it over while attempting to jump the spark. no spark. In all fairness the cap and rotor looks like garbage, but I would still see a bit of something, maybe a flicker.
I have not checked the timing belt (cam gear) or the distributor for movement. I will try that tomorrow.
I have a few questions I could use some help with.
1. Is there anywhere I can get good detailed instruction on using the OBD1 test port?
2. Is there anything very obvious to check that night me my golden ticket.
3. I have the factory diagnostic and system discernment manual, but I do not have a breakout box, does anyone know if the ports on the breakout box correlate to the order of the wires according to the ECC pin out sheet? (ex. is port 5 on the BoB that same as wire 5 on the ECC connector?)
That's about all I got people. please feel free to ask me questions and or offer insight.
