Check to see if your spark plug wires are not cracked or worn. They would make the engine run rough when cold or damp more often then when the engine drys up when warmed up- just an easy thing to check...

91 chevy cav z24 5 spd will not start @ times sounds like no fire other times sounds like no fuel.Replaced fuel pump,timing chain, crankshaft sensor,oil sensor,map sensor,body throttle accel sensor.st


Pull the air cleaner off and crank the engine. If puffs of air come come out of the throttle body when cranking the engine then the timing is not set correctly. Otherwise, after cranking pull a spark plug and see if it is wet with fuel and if so this indicates an ignition problem (coil, distributor/cap/rotor or faulty ECU).

97 geo tracker stops runing


If one of the sensors is failing, you should be getting a check engine light and a trouble code.
When you say it has fuel, do you have injector pulse and fuel pressure in the rail ?

Truck wont start after changing air filter


I am not aware of anything connected to the air filter box that would keep the engine from starting.
If you unplugged a sensor it should still start, just run rough and the check engine light would stay on.
Its possible a wiring harness got unplugged or something got shorted and you blew a fuse but thats not likely.
If you don't see anything obvious around the air filter, and all of the fuses are good, you may have to start from zero and find out if you are missing spark to the plugs or fuel pressure.

Try the cheapest Fixes first 1) change the air filter. 2) change the fuel filter. Add 1 can of B&G44K to a full tank of 91 octane fuel. This additive is the best on the market and only available through dealerships(Do not substitute). It will condition the fuel pump and injectors. Try this first, Then redo the ODBII test. Erase all stored faults after reading. Put a dab of RTV on the bare wires at the crank sensor to insulate wires.

Jeep will crank but not turn over without gas and rough idleing


Have your injectors, injector pump, fuel pump and filter checked. if you have a new motor, definitely check the fuel filter. Also, you could have a relay or sensor, have a tech put a diagnostic machine on it to check your electrical system.
