If you have wd 40 you can spray it into the intake and see if starts, if it don't can be a number of things e.g. low oil, computer chip,etc., but if it does start with the wd 40 may be clogged injectors or bad injector coils. Good luck Tim

It shut off while I was driving and now it won't start


The things to check are: is the engine still getting fuel and spark. Do you hear the fuel pump buzz on for 2 seconds with key in on? It has to turn on for 2 seconds to prime the lines and fuel rail on the engine-where the injectors sit. A fuel pressure gauge could be hooked up to test the fuel pressure, with key on. No pressure means the pump is not working right, not coming on. Either the pump has gone out, or the fuel pump circuit has a problem.

If gas is getting to the engine, then check for spark on a spark plug wire. No spark when cranking the engine over means there is a problem in the ignition system- spark plugs, plug wires, ignition coils (the coil pack), ignition control module, the pcm, the crankshaft position sensor-all of these components need to be checked. Buy a cheap spark tester and start there.

Won't Start


Pull a spark plug wire and check for spark. Just take a spare, working spark plug and put it on a plug wire (or take a plug out of your engine), and ground the plug hex or the plug threads on a metal piece of the engine. Now the plug is grounded, so you won't get shocked when checking for spark. But just in case, wrap a heavy rag around the wire, or use a glove to hold it, and watch the spark jump the electrode while someone is cranking the engine. A good ignition system will have a blue, snapping spark. If you have no spark, check a second wire, and still nothing, then the ignition system needs checked-the coils, ignition module, and crank position sensor, and so on. An orange or yellowish spark is also a sign of ignition problems.
If you do have spark when checking, then check if fuel is reaching the engine-the schraeder valve on the fuel rail is the test port for a fuel pressure gauge. Really what you need is to check fuel pressure, but if you punch the center pin on the valve, and gas squirts out, then you know gas is up to the injectors and under some pressure.

Engine cuts in and out


Hello, I would suggest looking at the fuel pressure on your fuel rail to check if the fuel pump is working properly. Sounds like a bad fuel pump. Also check your fuel pressure regulator.

Check for spark at the sparkplug, to see if everything in the dist. is working right. And check the injector harness for something being pulled loose when the wires were jerked out.

My 2002 chevy 1500 van , 4.3 liter v6, will not fire. ran great, no signs of trouble leding up to now. Cranks,cranks, & cranks but no sputter, fire, anything


I would check and be sure I had fire to the plugs and fuel to the throttle body. I read what you wrote about the fuel pump but then on the end of the description where you put gas in the van the pump might not be working. If so you could have a bad wire to the fuel pump or a plugged fuel filter. Once you verify those items I would pull the 02 sensor ahead of the catalytic converter in the exhaust and make sure the cat or muffler is not plugged. If they are it will put back pressure on the engine and not allow fuel into the cyl. to fire.

2003 kia Sedona won't. start


If this is a sudden occurrence and nothing suspicious happened prior, you most likely lost either gas or spark to the engine. You need to check for both.

Do you hear the fuel pump in the gas tank buzz on for a couple of seconds when you turn the ignition key to ON? Unless the fuel pump turns on and puts gas under high pressure at the fuel injectors, the engine cylinders won't get gas to start. Correct fuel pressure is crucial to know if you have a fuel pump (or fuel filter) problem. If the pressure is correct, it is probably not a fuel problem but a spark problem, although there are less common instances where a fuel injector circuit may malfunction.

The ignition system not producing spark at the spark plugs is the other common problem of no starts. Buy a cheap spark tester at a parts store, plug it into one of your spark plug wires, then crank the engine over and watch for a strong blue spark. You might need a helper to do this. If you see a consistent spark, the ignition system is probably good, although you should probably check more than just one plug wire-sometimes one bad ignition coil in a coil pack will cause no starting. Good luck.

My 95 olds cutlass ciera will start up and run for about 5 minutes, then start sputtering like it aint getting no gas, slow down then die till it cools off then starts back up, putting again, losing speed...


Check spark at spark plug using a spark tester and fuel pressure at the rail when it acts up. If the pressure is ok at the rail, but the injectors aren't firing, that can point to a bad computer.If the fuel pressure is present but the spark is not being supplied to spark plug wires to spark plugs, then an ignition module might be in need of replacement (the metal plate the coil packs sit on). If the engine has a service engine soon light before it dies, maybe check the codes that should be stored in the computer using an OBD-I scanner.

Car hesitates plugs are new wires are new on board scan says wire problem or plug problem perhaps coil pack??


Check each wire from the coil pack to the spark plugs with an inline spark tester. If you find that each wire has correct amount of fire, then check the fuel pressure at the fuel rail for correct pressure to the injectors. If you find pressure correct on fuwl rail,then look for possible injector not working correctly.

My truck will not start just cranks but will not fire


Air - not likely the problem ! mechanical cable controlled throttle body

Fuel- make sure there is gas in tank! fuel pressure test at the throttle body or rails, if no fuel check power to fuel pump: ignition power to breaker or fuse, relay , power to pump at 3 pin connector near tank/frame rail on drivers side, - if pump is runniig but insufficient pressure, check for mechanical restriction: plugged filter broken or pinched line, plugged pickup tube in tank. if good pressure to rail or body, check ecm : diagnostic codes, fused power, ecm tells injectors when to open, dependent upon several sensor parameter inputs.

Spark- ignition - coil-distributor-ignition module (or coil packs)- wires-plugs-ignition module (signals coil to discharge, mounted beneath distr cap) work backwards from plugs.

Engine will turn over but will not start running


start with the basics check for fuel fire and air check fuel peressure with a gauge should be 50 - 65psi
pull spark plug wire and place near ground if no spark in crank sensor or coil pack ensure air filter is cleaned

on fuel pressure if low check fuel filter pump may be working and cant get to fuel rail but could have damaged pump the fuel pump is controlled via crank sensor signal so no crank sensor signal no fuel
