Why no crank, no start?


I would check out the VSS - vehicle speed sensor for being shorted internally. This sensor get's a five volt ref. from the PCM or TCM which ever your vehicle has . Disconnect the VSS sensor connector an see if the vehicle starts . If the sensor is shorted it will bring down the data communication bus causing a no crank , no start on some make vehicles ! When you turn the key to the run position does the check engine light come on an then go off after a few seconds ?

My 98 Ford mustang runs good when u first start after driving it for couple minutes it will start stalling and loose power. If I turn the key off and on it start running good for a minute


run the fault codes
it appears that you have a coil problem that is failing when it gets hot
If not the coil then the ignition module.

My jimmy 95 stall sometimes, when I stop strong, and when start run at 2250 rpm and then go down at 250 and sometimes stall, then reestart and run normal, but is danger than motosa stall in freeway. Thanks...


i would take it to a nearby parts store and ask to use the OBDII -code reader it plugs into the drivers side under the dash ...once connected turn the key to the on position and when is says communicating with vehicle let it continue on after a few minutes it will give you codes as well as a readout of issues that it has found ...any parts you may need will be there and you will have an option to clear all codes after the fix ..but it could be a few things going on such as a failing fuel-pump cracked plugs /wires or a wire that is grounding out on the block because the wires run close to the motor area ...hope this helps you

1997 gmc k1500 runs really rich


Hi there,first of all you must synch the cam/crank sensors. To do this put the engine on top dead center remove the distributor cap and look very closely at the dist housing there will be a 6 mark and an 8 mark loosen distributor and rotate untill the rotor points directly at the 8. The marks are small so get a light and look closely.Clear codes and restart. Is vehicle still running rich?

1997 gmc k1500 seems to be running rich, very rich


If the engine is trying to flood, it will kill the engine. If you have the spider fuel system, it is noted for problems.
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, also, check fuel injector pulse.
I don't know if this may be a problem? below

Engine stalls when restarted idles up and down and stalls


I went through this scenario while working in a toyota sienna a few months ago and it ended up being the battery. When battery supply voltage starts to drop the PCM will limit voltage to certain areas.

Hello;
Check your fuel pressure regulator. Make sure you have a good vacuum to it and it is not leaking. 48 psi is a bit much and once it warms up will cause the vehicle to stumble and stall. Code 12 is a normal system.
Hope this helps.
Thanks;
