Thanks for choosing FixYa and welcome to the site. As far as the pump goes, you probably have a bad wire in the harness somewhere. Make sure you check the fuse, relays, and reset, if equipped. If they all check out, test it with a voltage meter and make sure your getting power at the connector. If not, test those wires. There are many things that can cause no spark. It could be the distributor, dist.cap, rotor, coil pack. It could be a cam sensor. It could even be the computer. Once you check the parts and if they are ok, it could also be an electrical issue. You would then need to check distributor connection for power or coil, whichever one your vehicle has. When it comes to finding electrical problems, it can get complicated. If you can afford it, the best way is to put it on a diagnostic machine. You could also try to get a code off your computer as well. Those are probably your best bets. If you can't, you just need to start checking what you can and go from there. If you have any questions, I would be glad to help. Thanks for using FixYa and best wishes.

2004 olds alero. new fuel filter and plugs. still wont start.


Did you check for spark at any ot the spark plug wires/ coils? If there is, check for fuel pressure at the fuel rail. Take the port cap off and connect a fuel pressure gauge. If one is not available, with a pocket screw driver deppress valve at port and observe if fuel pours out. If no fuel comes out at all, check your fuel pump circuit. Check for good ground and power at fuel pump connector. If power/ground are ok, replace fuel pump. If spark and good fuel pressure is present, there is the possibility of engine mechanical issues(jumped) timing chain). Also, a plugged catalitic wont let engine start but its very unlikely thats your problem. Start with your basics: spark, fuel, engine mechanical and catalitic.

2003. Why is no gas getting to the fuel rail?


Could be a "fuel pump relay" or ford equivalent that converts ECU fuel output demand signal to power to the fuel pump. To test jump direct positive to fuel pump and see if you get pressure at the rail. If you get pressure, that may be part of the problem. If not enough pressure (but measure) you may have a fuel pressure regulator or ford equivalent issue.

Change the fuel pump and still won't start on a 2002 chevy avalanche


Check for spark to the spark plugs, while cranking the engine. If no spark, you could have a bad ignition module, or a bad crankshaft position sensor. The crank sensor sends a signal to the computer, to start the fuel pump and signals the ignition module to start firing the spark plugs. It also drives the tachometer through the computer (PCM) Powertrain control module. The ignition module can be removed and taken to a parts store to have it tested. The crank position sensor is not as easy to test. Easier to just replace it. Good Luck. But wait, I have seen people replace the fuel pump, checked the fuel pump harness for power, and all was good. However, if the fuel pump does not have a GROUND, it will still not operate. Might want to check that. Have fun.

Acts like it's not getting gas


Poor accelleration, stalling, running rough at idle, low power are symptoms of poor spark. With engine running, remove and replace spark plug wires one by one. when you do this you may note that the engine becomes rougher or quits on certain plugs, and does not seem to change at all on one of them. the long plastic boot has a rubber insulator at the end of it. Spark has been known to jump from this seam over to the metal tube, effectively killing that cylinder, making it seem as though you have a fuel problem. If it is really a fuel delivery issue, the pump is accessed by removing the rear seat. under that is an panel that gives acess to the pump/level indicator assembly. The fuel filter is typically on the firewall, left side (follow the tubing going to your fuel rail , you'll find it.)

No power to fuel pump and no spark jump power to


Spark comes to the plugs, via through the ignition switch ( in the on position) to the primary side of coil. Possibilities ignition switch, distributor cap , rotor, plug wires, coil, control module. If you remove the coil, control module these can be tested at Autozone for free.
