We are not sure why you are having this issue.. many times you have been told/asked to do a leak down test, compression test, as well as check your timing. You seem hesitant to do this things and im not sure about your financial status but if you are unable to perform these test, my .02c would be to take it to your local mechanic and have the run the diagnostic for you. Your throwing parts at her when those parts may not have needed changing. The money spent there would have been more than enough for a mechanic to check your situation.

Stop asking questions and getter done.. Compression and leak down should be the NEXT thing you do.. Rent the kit for compression/leak down from your nearby auto parts store.

if you are getting exhaust out of the air intake, i would say you have one of two issues:

1 - Your timing is off, and needs to be reset to the correct location. This would cause the valves to not be fully closed at the correct time - not allowing for the compression needed to start the engine and keep it running.

2 - Your timing is correct, but your valves are not sealing properly during cranking - causing loss of compression, and the inability of the engine to run. Run a compression or leakdown test.

Either way, stop throwing parts at it - no "part" will solve your problem. You need to have tests done to determine where the internal failure is happening. It sounds like a timing issue to me and should be easily fixed by a mechanic who knows what he is doing.

if your compression is gone then your engine is gone. you could get lucky and have bad timing. thats an easy fix. if your valves are gummed then you have a bigger problem. if you have all this money to buy parts then why arent you getting it tested? you chouldve just taken it somewhere first. there arent many mechanics on the forums. most are DIYers throwing words around. im not knocking anyone here. just take it to a mechanic and get the real answers

as a mechanic im telling you to bring it to a mechanic. the first thing I would have done was hook up the scanner then a fuel pressure test, then check for spark, then a compression test maybe a leakdown test but people like you make people like me lots of money

Did you check your compression yet? Or do a leak down test?
