Most of the time the car starts however having trouble starting sometimes the engine turns over but won't start checked fuel pressure and it is 35 lbs. With key on replaced fuel filter replaced spark plugs replaced starter really replaced air cleaner filter
received no codes that indicate problems inspected spark plug wires and spark and appeared to be OK

Hi:
When this happens, check spark and listen for the fuel pump. If you don't hear it, I want you to check the Electronic Engine Control (EEC) relay. It's in the power distrubtion box under the hood (I think passanger side). Swith the relay with another one with the same part number to see if it makes a difference. You may also just want to check to make sure there is no corrosion and it's tight. This relay will shut power to the ignition and the fuel pump.

My truck will turn over fine but wont start. I have replace many of the sensors. It started off just idling very low and now wont start at all. The check engine light came on at the same time the rough idle started. I dont have an inexpensive way of getting it to a diagnostic machine. Could it be an ignition coil? There is spark on the plugs but how do I really know if its enough?

Firstly check you are getting fuel to the cylinders. If your getting spark and fuel it should be at least trying to fire up? Crank engine over a few times then remove a spark plug if it's wet and smells of fuel your getting fuel. So we need to check further. Let me know?
