That the mass airflow sensor had a low voltage rub alcohol on it works well
Hmm. Id check starter connection maybe teeth arnt catching to start. Not sure. Hopefully someone will be able to give some advice
It just turns over can it be the throttle body that's stopping it from cranking any ideas could any sensor or relays keep it from cranking open for any ideas bout to drive me crazy just bought the car runs great when running cut it off and it hasn't started back until I changed tha fuel pressure dampers and fuel pump and relay but wen I went to change the battery it was doing it all over again ??
seems to be a fuel issue. When it cranks over. Or finaly starts does it have a rough idle or does it purr like normal? One simple thing to do is check all fuses in the engine bay box an inside ur cab for fuel related fuses. Theres no codes showing now? (Main point. If there was a code an u swaped a part it needs to run the pcm over again so it can chack all relays an switchs to make sure its running properly then ur pcm will set its self up to run with your new part(s) . but if u havent had the car running sense the swap its not gunna run right bc it hasnt had time to re program its self)
It only started one time since I put the new parts on it and it only turns over you say it hasn't had time to reprogram itself how does that work
So anytime u swap parts like sensors or relays u need the pcm to run a full diagnostic of the car. If u had a bad air flow sensor ur pcm will set its self up with the bad part allowing the engine to run with it. Now that it has a new part it was to rerun it to the way its supposed to run. So sometimes bc u cant start the car it actually wont start bc its still telling the Brian of ur car it has a bad part. Or could be a even bigger problem. Have I put a obd2 reader on it to check engine codes after the new part? (Your still getting power to everything tho right)
Yeah power is to everything today I go out I sit in it for a little while the doors lock me in without me touching anything so I pulled out the key I hit the unlock button on the key chain and it crunk right up only to allow me to ride around and turn it off turns back on and then start doing it again won't start right now
How many cold cranking amps does ur battery put out.
Battery put out 750 cold cranking amps just went and tried it just doing something it it caught barely so I press the gas it died out it has never done that before it actually crunk but wouldn't let me press the gas and once it did allow me to press the gas it only let me get the RPMs to about 3 and then die down the cut off
Did it get the right fuel an is it the right pump. Hoenstly it sounds like a fuel issue. But idk man this is stumping me!!!!! Ur engine is not getting enough fuel but without looming at it i cant say.
Do you know any for sure ways to find out if it's not the key not sending a signal for the engine to fire off
