2001 expedition crank but won't star


You check the basics, if it cranks good but won't start, have a helper crank it while you check for spark at the spark plugs. If spark everywhere, use a gage and check proper fuel pressure and fuel injector pulse. Any applicable trouble codes? What about your security system, where applicable?

94 Buick Roadmaster cut off & won't start it turns over but won't start i replace optispark and ignition core star and fuel pump still kicking do you think you would be the camshaft position sensor


First you want to know if your ignition system is working, so have you checked for spark?
If the answer is no, go to a parts store and buy a calibrated spark tester, real simple and inexpensive. Hook it up to one of your spark plug wires, crank the engine over with the key (as if you were starting it) and see if you get a strong blue spark. You will need a helper to turn the key while you watch for spark on the tester. If you have good spark, you can assume the ignition system is working good, so that's not the problem, nor is the cam sensor a problem. If you have spark and still no start, it likely is a fueling problem- see if fuel pump is turning on, check injector circuit-things to do with the fuel.
If you find no spark when cranking, something in the ignition system is the problem. Not necessarily the cam sensor- that sensor is for the computer to synchronize fuel injector timing with the intake valves opening. For the computer to determine spark timing and advance, it uses the crankshaft position sensor. So that sensor is more tied with the ignition system, and is often at fault when spark is lost. Other things, too, like the ignition control module, but those are things to check when troubleshooting the ignition. A repair manual should have a troubleshooting flow chart, or at least some steps or procedure when troubleshooting the ignition. Good luck.

1600 roadstar coils check good but have weak spark


Hi, Anonymous and the usual suspects are:
1. Fuel tank empty.
2. Fuel supply valve/petcock turned off.
3. Fouled spark plugs.
4. Engine flooded as a result of overuse of the enricher.
5. Vacuum hose to the fuel supply valve/petcock disconnected, broken, cracked, or pinched.
6. Fuel valve/petcock or filter clogged.
7. Fuel line to carburetor or throttle body pinched or kinked.
8. Carburetor float stuck.
9. Fuel injectors clogged.
10. Severely discharged or damaged battery, you need 12.5 volts or better and be able to pass a load test if necessary.
11. Check battery terminals for damage or corrosion, check the battery cables at "BOTH" ends for loose, corroded, or broken connectors, "INSIDE" and outside the cable harness, perform connector wiggle test and check cables with an ohmmeter if necessary.
12. Loose or corroded wire connection at the coil, battery or plug between ignition sensor and CDI box.
Spark plug cables in bad condition and shorting check for leakage in the dark, cable connections loose, or connected to the wrong cylinders.
13. Ignition timing incorrect due to a faulty MAP, CKP, O2, TPS, sensors.
14. Faulty neutral, clutch lever, or kickstand safety switch.
15. Faulty fuel pump or fuse or relay.
16. Faulty CDI box.
17. A stuck bent or burnt valve.
18. Tip over sensor needs a reset.
19. Check for engine trouble codes.

My Mitsubushi Space Star Car won't Start. What can I try?


spark plugs are deep in the head yet you should get all the the old fuel out first, stale fuel wont ignite and will also clogg fuel filter. you need a mix of atleast 70% new fuel even then its not good for the injecters. If its a manual gearbox a tow start is a quick fix although no go for auto's. cant be much wrong if car was fine when parked, plugs-fuel-filter and possibly fuel pump for sure. If that doesnt fix take plug out put in lead and crank engine to be sure you have spark even just put any plug you know works in lead leaving your plugs in engine just to check for spark y turning over engine looking for spark on plug good spark will be blue but any spark is good.

2001 V-Star Classic won't start


A yellow spark is a weak spark. A blueish white spark is normal. It sounds like the CDI is not in good shape. A dealer can quickly check the system and tell you what the bike needs.
