Fuel Pump? Just keep trying things?

Do you have fuel pressure at the engine
& what is it?

Spark was low? (weak?) How was that tested?

SOURCE: my 1996 cavalier Z24 wont start

pull a wire and ground it via useing a screw driver at the end of the spark plug boot to check for spark / if their is no spark / ignition control module / there is also a crank shaft position sensor / located on the back side of the motor under the coil packs / pain to get to / also the nuetral safty switch / to check the neutral safty switch diconnect the big harnest at the neutral safty switch put a fuse tester to the yellow wire / have someone turn the key / with the tester grounded the light should come on / now we know the ignition switch has power going through it. if there is a no power at the yellow wire / bad ignition switch / does the car have a relay located at the top of the radiator core support (up by the radiator looking down drivers side)if it does not gm will install one for free / if there is / look for the purple wire coming out of the relay and Follow it down to the starter / reconnect the neutral safty swtch / touch the small S (the smallest screw) terminal on the starter soilenoid / have someone turn the key forward check the light / this will detemine if the relay is good / CAREFULL NOT to touch the big starter wire with the little one it will jump the starter / I HAVE THE SAME CAR / Hope this helps

If this engine is a VORTEC then you may have a problem with the internal fuel system. Under the top plenum there is a fuel reg and poppet valves that inject fuel into the cylinders. Sometimes the tubes that run fuel from the reg to the valves can leak and cause your problem. This cannot be found with pressure check because this occurrs after the reg. PS fuel mileage will go down. Let me know if this helps.Moe

Looks like you've covered the basics, make sure the firing order is correct with your spark plug wire replacement. Hope this diagram helps.

Car Won' Start


Car won't start?
First thing would be to check all your fuses. Most fuse boxes are located under the driver side dash panel. Some cars do have an extra set of fuses on passenger side kick panel (foot area on door side)
If all fuses are good, then next thing would be to test your relays with an ohmmeter.
If all your your relays and fuses are good, you will want to check for fuel and spark. A car needs air, fuel and spark to run.
To check for spark, you can purchase and use a spark tester.
If you cannot obtain a spark tester, then the next best thing would be an ohmmeter. You can test the power coming from your coil packs or distributor depending on what you have. On distributorless vehicles (one with coil packs) the coil pack are attached to an ignition module. This module is powered by the Crankshaft Position Sensor. This sensor can be tested with an ohmmeter. The Crankshaft Position Sensor is the first thing to be tested if you have no spark in any cylinder. If you have spark in some cylinders but not all, then check the coil pack (1 pack per 2 cylinders).
If you have a distributor, test the coil that provides the spark.
If you have plenty of good strong spark, then the next step would be to check for fuel.
Fuel system consists of Fuel Tank, Fuel Pump, Fuel pump Relay, Fuel Filter, Fuel Pressure Regulator and finally carberator or injectors.
Fuel injected systems have a fuel rail. On the fuel rail is a test port for fuel pressure. If you have a fuel pressure tester you can test how much fuel pressure you have. Or you can place a rag over the valve and press it in to see if there is pressure. If not pressure, check that pump is running. You should hear it run for a few seconds when key is first placed in the ON position. If pump is not running, check fuses and pump relay.
If pump is running but fuel pressure is low, check for leaks, plugged fuel filter, or leaky injector.
If your check engine light is on, then you likely have a faulty sensor or circuit and should have the engine codes read with a code reader/scanner to pinpoint exact problem area.

S10 blazer lacks power, bogs under acceleration


Check your coil output, buy a cheep spark tester. Pull of a spark plug wire and plug in the tester(ground the other end), set it to bridge a gap for 30,000 volts.Have someone start it and make sure the spark will jump the gap on the tester.Danger-Very high voltage! It will light you up if your touching the tester while the car is running!You'll be able to see a bright blue spark(and hear it as well) if your coil is good.If it's a yellow thin spark it's probably the coil.
If you have good spark, check the fuel filter and fuel pressure at the fuel rail.
Back firing could be timing,cam position or crank position sensor.Worst case scenario, timing chain or belt.

Galant Special Edition 1994 Motor does not start


this maybe caused by no fuel or faulty fuel pump, ignition coil, wire and plug crank position sensor. first check for spark by removing on spark plug wire and put a spark plug in the spark plug wire boot, donot touch the plug only the boot have someone crank the car over. if you see spark, that part of the ignition is good. if not, check the coil resistance if should 40 to 80 ohm with a volt meter pf not replace. if ok, but no spark check the igniton control madule make sure the coil and module are receiving current. if not check the fuse that feels them. if it is ok, check distributor cap and rotor. if rotor and cap are fine, check for fuel at either the fuel filter, the fuel return line or removing some spark plug and see if they are wet. if there is no fuel check the fuel pump and the fuse and relay that control the pump. if there is fuel with high pressure but there is no spark, check the crank sensor for signal with a volt meter while cranking the vehicle

Engine cuts out on acceleration


could be the pump or injectors or both. while your at it check your fuel tank for rust dirt any thing.
