2006 dodge 1500 wont start


Make sure battery has a full charge and battery connections all good. If it cranks good but won't start, have a helper crank it while you check for spark at the plugs. If spark everywhere, use a gage and check proper fuel pressure, also, check fuel injector pulse.
Any applicable trouble codes?

97 gmc 1500 350 5.7 new fuel pump and filter it cranks over but wont start


Kelly, could be a few issues, security lock out, crank sensor, fuel pump fuse/relay, faulty new pump,faulty ignition switch, etc. Attached links may help you diagnose the crank no start issue you are having.
Check the attached links,video,instruction and guides, Good luck

How would a ignition output signal stop my 1995 honda accord from starting?


The motor turning over & cranking---- is one in the same

You have a :
NO CRANK or a NO START !!!

You checked fuel pressure at the motor
You checked for spark or injector pulse
The battery is good-you tested it

Now tell use about the loss of ignition output

Where is all that coming from--in detail

Have to crank sensor scoped

Is the ignition switch worn out ?

1989 cutlas cera wont start its giving me code 12


Code 12 is a "good" code-it means system normal.
Since no codes are stored, check for spark and check for gas-is the fuel pump coming on? You should hear the pump buzz for a couple of seconds when you turn the key to on-it should start and pressurize the lines, then shut off until the engine is cranked-when cranking, pump should be running again. If you don't hear the pump, check if the fuel pump wire at the gas tank connector has power to it when the engine is cranking. If it does and the pump is not working, the pump will need replacing.
If no power, check the fuel pump fuse and relay, under the hood.
If the fuel pump is working, it may be ignition related-check for spark. You need to see a blue snapping spark to know the ignition system is good. If no spark, suspect the ignition control module or the crank position sensor -or the pickup coil, if no crank sensor. The pickup coil will be in the distributor-if you have one. If no distributor, crank position sensor is behind the crankshaft harmonic balancer.
If fuel pump and spark are good, you will need to diagnose the injector circuit.
Post back with what you find.

My 98 gmc 1500 V8 5.0l won't start. Has good spark


Spray starting fluid into the air intake of the engine, if it starts and you have fuel pressure you have no injection or injector pulse as we call it. Check ECM fuse one and two for continuity if it starts with fluid..

My 99 Gmc jimmy will not start. the fuel pump is good the fuel filter is not clogged, i replaced the neutral safety switch, plugged in my code reader no codes, i believe it is the starter or the ignition...


Does it crank or not? If no crank then look at the starter or ignition switch. If crank but no start then look at the ignition system. Check for spark at the plugs and also check the fuel pressure. If there is spark try spraying a little starting fluid into the intake. See if it starts and stays running. If it stays running reply back and I will explain why.

I have a 96 chev blazer it had a leaky fuel line i replaced it it fixed the problem , after a few months it wouldnt start so i sprayed starting fluid and it got me 60 miles now wont start i replaced fuel...


Injector pulsation in control by your E.C.M quade driver none repairable computer just get's replace to fix the problem, good luck. Also one more thing check your E.C.M fuse.

1997 Chevy Silverado 1500 4x4 will not start. Getting spark checked all fuses, changed rotar - spark plug wires,


Have you checked the fuel pressure? Fuel pumps are a common failure item on those trucks. Pick up a cheap fuel pressure gauge and hook it up to the shrader valve on the fuel rail. With the ignition on and you should have 55-65psi. Even if it's a few psi below spec it could stop the engine from firing.Once you determine the fuel pressure isn't adequate make sure you have a good power and ground at the fuel pump. If that checks out, time for a new fuel pump module. I recommend only replacing it with an AC delco unit, I've heard bad stories about aftermarket replacements.
You could also spray some carb cleaner or starting fluid in the throttle body and crank the engine over. If it runs for a few seconds after spraying starting fluid in you know you have a fuel delivery problem.

Cranks but wont start


Engine Cranks But Will Not Start

For an engine to run, you need three things to happen inside the engine. Compression, fuel and ignition, without any one of these components the engine will not run.
Basic Checks:

A. Test Fuses. Test both under hood power distribution center and the fuse panel under dash. This is done with a test light tool. The test light should illuminate on both sides of the fuse, if not the fuse has failed and needs to be replaced.
B. Testing Fuel Pressure Test for proper fuel pressure with a test gauge on the fuel rail, most throttle body injection cars (TBI) are between 13 psi and 17 psi. and most (DPI) direct port inject systems are between 40 psi and 55 psi. If no or little fuel pressure is observed and there is 12 volt power present the fuel pump, the fuel pump needs replacing.
C. Checking Timing Belt Test for compression by removing a spark plug and insert a compression gauge. Crank the engine over about 5 seconds the gauge should read between 125 psi and 165 psi, if no compression is observed remove front engine cover to inspect timing belt or chain. Crank engine to observe cam rotation, if the cam does not rotate the timing belt or chain has failed. (note: if the timing belt drives the water pump it is best to replace the water pump at this time)
D. Test for Injector Pulse Remove injector connector to insert injector test light (node) or volt meter. Observe light flash or gauge pulse while cranking. If light/voltmeter doesn't respond, an ignition distributor/crank angle sensor (CKS) or an ignition module is most likely your problem.
E. Test for Ignition Spark Remove spark plug wire, insert an extra spark plug into end of wire, rest spark plug next to a ground source then crank engine. You should observe a blue spark between the spark plug gap and ground source. If no spark is observed, an ignition coil, ignition rotor or spark plug wires might have failed. (always keep hands away from engine when cranking)
