My car won’t start I have a 2004 Chevy Monte Carlo 3.4 l, some guy told me it was my E.G.R valve I changed it nothing it cranks but still don’t start,I changed my fuel filter cause it clogged it started for a bit turned it off then didn’t start again but cranks but don’t turn over or start, I took out the air filter cleaned out the air filter with carbon cleaner it started for a bit again then next day went to start it cranks but don’t start up. That’s my problem Mechanic's Assistant: Is the fuel filter an external one, or is it inside the tank? Underneath or the bottom of the car Mechanic's Assistant: Are you fixing your Monte Carlo yourself? What have you tried so far? Honestly a couple street wanna bees and 1 mobile mechanic. I tried just the fuel filter but the 2 codes popped up one code we fixed and cleared the other was the crankshaft position sensor but my street mechanic took out the plugs the back one my car has 2 that was 4 days ago he has not come back and still have my plugs Mechanic's Assistant: Anything else you want the Mechanic to know before I connect you? I changed E.G.R valve,map sensor,fuel regulator,alternator,air filter,[radiator](/topics-radiator-chevy/),new battery,temperature sensor, transmission from a 2005 Chevy Monte carlo,power steering pump,and thermostat,and turpentine belt I think that’s it

Sometimes it may take a moment for me to respond because I may have to look up information about your concern. I appreciate your patience and will provide responses as soon as possible. Ok, first, was the crankshaft position sensor replaced and if so, was the relearn procedure done using a scan tool? Second, has fuel pressure been tested with a fuel pressure gauge? Third, when you turn the key to on position does the security light which is a padlock symbol, flash on and off, come on and go off within 10 seconds or stay on as long as key is in on position?

No my street guy still have the plugs,2 No it has not had that test done,3rd it flashes just security then goes off but the if my car just sitting it has my car lights flash on it's like every 15-20 min
Automotive Expert
HI Ok, unfortunately there is not alot you can do at this point until you get the plugs back and installed. At that point a fuel pressure test needs to be done. With the fuel filter having been clogged, I suspect your fuel pump is also and needs to be replaced, but will need to be confirmed by doing a fuel pressure test. It should be 52-59psi with key on [engine](/topics-engine-chevy/) off. If under that, replace the pump Thanks for using Just Answer and letting me help you. I hope I provided what you needed. If you find more help is still needed, let me know by listing out any remaining questions you have on this concern. I hope the remainder of your day is well.

HI, There is not a reset button for this. The computer has to be reflashed with a dealer level scan tool
