1994 Ford Explorer

The last time I was on here I receive some very great info from a great mechanic. He told me what the 2 codes meant that Pepboys Auto pull back in July from my truck.

332-Knock Sensor
335- Crankshaft Postion sensor

I havent yet to get it fix. I'm so confuss. I have heard lots of different folks tell me that I may not need Knock Sensor, it's the Crankshaft. However my check engine light is still on. This happen right after having new module install. I have had many new parts install, and the problem still isn't fix. I taken my car to see if it would pass emission testing, and it actually did w/ the check engine light on. I notice my car was running sort of poorly. Yesterday, tried to turn it over, and it wouldn't start. It has plenty power when I turn it over, but will not crank. This was the very same problem I had in very beginning, I was told it was the crank sensor. I purchase & had that place on car. It crank after that, but now it's back to same result. It has to be something else now because I have already place crank senior. Any suggestions. I can't even get my car start to go to a shop.

I'm not sure. I tried to just turn switch over to see if I hear the click noise before cranking it. I do not think I heard anything. I'm just not sure. How do I truly found out rather I'm getting spark from fuel or not. I do not know much about cars at all. I have attempt to contact a mobile mechanic.

Not a problem. Here are the how to's for checking both. You will need a fuel pressure gauge, but most parts stores will lend or rent them to you. Review the directions and let me know if you have questions. Also, the fuel pressure directions have a video to review. The tech explaines what to look for regarding everything related to the fuel pump, fuel pressure regulator, and fuel drop off.

Let me know if you have questions or if you need help.

Thanks for that info. However my car did end up turning over this morning. It seem to be a electrical problem. My computer reset itself yesterday morning. This morning, I tried to see if it would crank, and it did. The 2 codes that pepboy pull back in July may be the problem. The mobile mechanic told me it may be the second code, crankshaft position sensor. I need my issue resolve, as of now I still do not know the problem.

The crank sensor could be the problem. However, often they create a problem after the vehicle warms up.

Yes I know! However I have already had that install. I've had so far. Module, crank sensor, new battery, water pump, . However my check engine light comes on right after module was install. I was told to drive car. Mechanic says. My computer may trying to respond to module. Check engine light never turn off. Some of the parts were second guess, so as you see I have spent out money not needed. I really do think I needed the crank sensor & battery though. I'm not sure whats causing my car computer to keep reseting itself. Its as if it will run for sometime, then other times it will not crank. A day or so, it ends back up cranking up. I'm not sure whats the problem, however it just may be the second code this time around. One mobile mechanic told me that he couldn't perform test because car is now running. He says in order to found out whats wrong, the car would need not to be running. First time I heard that.

Has the starter relay been checked? You mentioned that there was a clicking when the vehicle started.
