SOURCE: wont stsrt

sounds very much like the coolant temp sensor
, this tells the pcm that the engine is cold, sometimes they fail and tell the pcm the car is at -40 degrees, the pcm then tries to compensate by keeping the injectors open for too long flooding the engine. the part is inexpensive, and normally easy to replace. It can be checked with a scan tool, or a volt/ohms tester,

Injector pulse comes from Cam sensor, If you have a BAd CAMSHAFT sensor you will not get injector pulse, replace sensor and that should solve your problem. Good Luck and thanks for using FIX YA

Got a 2005 Nissan Altima it run for a bit can come up to a stop sign it will just die take 20 min before it will start again


well you need to identify what is missing. An engine needs ignition spark, fuel and injector pulse to start. (assuming mechanically the engine is ok. Like good compression and cam timing ok) A fuel pressure test is needed to see if it has good fuel pressure. Test for spark and injector pulse. If the fuel pressure is ok but it doesn't have spark or pulse it is usually and crank position sensor but on Nissans it could also be a faulty cam position sensor. Without the proper test equipment you will need to have a qualified mechanic diagnose it for you. I wouldn't start throwing parts at it.

I have a 2000 Nissan Altima GXE crank no start no injector pulse no spark, new crank sensor new distributor.


You have made no mention of any diagnostic testing most importantly does it have any fault codes showing on a scanner?

No Injector Pulse


run fault codes as there is a problem sensor in the system. volts at the injector is suspect as the voltage will vary with the fuel requirement.

My 2002 nissan sentra will crank but won't start. i've replace the ecm/ecu, the cam/crank sensor or position, checked the fuel pump/pressure, and it still is doing the same thing. sometimes it


I assume you checked the fuel pressure and it is normal.
Are the spark plugs getting spark when it fails to start ?
Are you getting injector pulse from the computer ?
Any trouble codes stored in the computer ?

On spark


If it where the crank sensor there would be no injector pulse also. If it where the cam sensor you could have unplugged it and see if the car started. I think this one may have a simpler solution. Have you checked for power to the coils? Have you checked the coil fuse or the ECM relay?

My Altima SE R will not run. I replaced the fuel pump, but we are learning that there is no pulsation to the fuel injectors. We checked out the immobilizer and its fine, all the cam sensors are fine, the...


First guess is anti theft.
Leave key on for half an hour and/or lock unlock doors with remote.
Does the tack on the dash show rpm when cranking the engine?If it does you should have a injector pulse using a noid light.
If you have rpm showing and no injector pulse try borrowing a computer from a vehicle like yours.
No RPM showing when cranking?
Check/change crank and cam sensors and possibly computer.
Cam timing can cause no start but you should have an injector pulse even with a jumped tooth or two on the timing chain.

2002 nissan altima, no spark, no injector pulse, no start


nissans have an issue with crank angle positioning sensor, you must remove it and check for resistance, it definetly sounds like it cause crank sensors sometimes work when cold then shut off.
