Engine not starting

You have to check for spark too. You can have a crank/no-start from no fuel injector pulses or fuel pump, or from no spark, but about 95 percent of these are caused by no injector pulses and no spark. Too many people get hung up on the first thing they find missing and fail to look at the additional symptoms.

Be aware too the fuel pump runs for one second when you turn on the ignition switch. That is where you will get the correct fuel system pressure readings from. What's important is whether the pump resumes running during cranking. If it does not, you will not have spark either because both systems are turned on by the engine computer when the engine is rotating, and it knows that from the signal pulses from the crankshaft position sensor and/or camshaft position sensor, depending on which engine you have. It is real common for those sensors to fail by becoming heat-sensitive, then they work again after they cool down for an hour. Most commonly these fail after a hot engine has been stopped for a short time, as in when stopping for gas. That gives the engine heat time to migrate up to the sensors and causes them to fail. With that type of failure, diagnostic fault codes for these circuits usually do not set just from cranking the engine.

You have the less-common condition where the engine stalls while it is running. If a fault code is going to set, that is the condition it is most likely to do it under. Start by having those codes read and recorded. List those numbers in your next reply and I will interpret them for you. The people at many auto parts stores will read those codes for you for free.

Look for the fuel pump relay in the under-hood fuse box. You can remove that, then jump the two terminals in the socket to feed 12 volts to the fuel pump. Unfortunately I can't tell from the diagram which are the correct two terminals. Instead, another way to do this is to pop the cover off the relay, install it that way, then squeeze the contact. That should cause the pump to run. If it does, you know that part of the circuit is okay. If it doesn't run, you can put a rubber band around the relay to keep it energized while you take test measurements in the circuit. Also check the 15-amp fuel pump fuse.

Will the engine run if you spray starting fluid into the intake? Also did you say the spark was present?
