Well. To no freaking surprise the replacement of the sensor did nothing! Still no spark.. I want to dump this car in the river! I don't even know what to do next. Anyone know where the ASD relay is? Could this be the problem? How can I be sure votage is going to the distributor? How can I be sure the fuel pump is coming on? I don't hear anything but not sure what I'm listening for. I am so frustrated with this car.

I feel like I'm talking to myself.. But thats ok, hoping someone stumbles across this and tells me the one thing I am missing.
Anyways.. Found the ASD relay in a cluster of 4 behind the PCM. They all looked the same including the starter relay. So, I switched the ASD relay with the starter relay and still no spark, but the starter worked so I know the relay is good. I need help.. How do I know if the fuel pump is coming on? |
You could run a fuel pressure test using a pressure gauge and the necessary fittings. You could get a rough idea if the fuel pump is working by relieving all the fuel line pressure and then re-connecting the system, turning on the key and listening for the pump to come on for a couple of seconds to build pressure back up. It won't tell you if the pressure is high enough to work properly though. I don't think there is any code for low fuel pressure, so if that's the problem, it won't show up as an OBD reading.

If your cam/crank sensors are not in sync you will get no fire. Check your timing belt. Does it sound funny when you crank it over?

When you say cam/crank sensors in sync how do I know if they are or aren't and how would I fix that? I honestly didn't think about the timing belt at all.. I'll check that for sure. |
You have to read the cam/crank signals sync on a scan tool. Funny as in sounds more like an air compressor than an engine turning over.
