If a 1995 Jimmy is not receiving an injector pulse, it could be due to several issues. Common causes include a faulty crankshaft or camshaft position sensor, which can prevent the engine control module (ECM) from signaling the injectors. Additionally, issues with the wiring or connectors, a malfunctioning ECM, or a blown fuse related to the fuel injection system may also disrupt the injector pulse. A thorough diagnostic check is recommended to pinpoint the exact cause.
What else can I help you with?
What is wrong when a 1996 Saturn SC1 will turn over but not start?
check for fuel pressure/ and then check to see it its fireing. no fire could be a coil pack or/ computer. no fuel could be fuel pump or filter or injector pulse.
Freightliner truck with an N14 Cummins that misfires under load what is wrong?
with an n14 it more than likely is an injector .. it could be air in line or turbo boost sensor but more oftenthan not its the injector
Your 2004 Pontiac Aztec service vehicle soon light came on what could be wrong?
it could litteraly be anything, from a bad sensor, to a stuck injector, to low air in your tires. have the code scanned, its cheap and can usually tell you whats wrong
What could be wrong if a 97 gmc jimmy gets no fuel?
Your fuel filter could be clogged up or you could need a new fuel pump.
What is wrong with a 1997 Chevy blazer s-10 if the 1st cylinder is missing but the other 5 are fine?
If is has spark, it could be a faulty fuel injector.
If a 1989 Jaguar XJ6 will not start but you have a have spark and fuel and pressure is delivered to the injector pipe however no fuel enters any cylinder what could be wrong?
AnswerFuel injectors are not opening. They open by electrical pulse from the ecu. You could have a short, a broken wire, perhaps a bad fuse or the ecu could be defective.You also might have a bad crack sensor on the front of the engine. ECU doesn't know the position of the cylinders therefore no activity to fuel injectors etc...
If a 2001 ford focus turns over but doesn't start and jump starting it won't work what's wrong?
You need 4 things for an engine to run. An unobstructed air source, compression, good fuel at the right time, strong spark at the right time. You are missing one or more of those things. If the engine is spinning over real fast without any resistance, you might have no compression, which could be due to the timing belt having jumped time. You could have no fuel pressure, due to a bad fuel pump. You could have no spark due to a bad coil. You could have no injector pulse due to a bad PCM or some other problem with the engine control system. Check air intake, fuel and fuel injector pulse, spark, and compression. Find out what you are missing, and you will be able to narrow it down to what sub-system is causing the problem.
You just put an engine in a 98 Plymouth breeze the old engine ran fine ran out of oil locked up the junkyard engine you bought nothing wrong but now you have crazy injector pulse and spark?
you need to get the computer realigned by a technician to match the motor you installed
Could a tune up and fuel injector clean up have caused a P0300 code and the catalytic converters to go wrong?
i think no, because dtc p0300 comes when the engine misfired detected, engine tune up and injector cleaning are need to perform when this dtc p0300 was set
How do you remove the hand brake cable on a 96 gmc jimmy?
Hand brake? I thought the last GMC with a hand brake was in 68, but I could be wrong.
Is jimmy graham from New Orleans Saints married?
Nope, don't think so, but I COULD be wrong, but I don't think I am. So just stick with no! Why?
1997 Chrysler concord with a p0305. I swapped the injector and spark plug with other known good ones.The plug wire is jumping a 30000 V gap on spark tester.whats wrong?
Try swapping the coil with another cylinder. If that doesn't work, use a noid light to check for fuel pulse at the injector wiring connector and a 12V test lamp to check for pulse at the coil electrical connector. If none of this helps, do a compression check. If compression reads normal, check your fuel trims for positive trim at idle indicating a vacuum leak, and check for a vacuum leak at intake gaskets.
