Not anymore, they changed the oxygen sensor cause that was the code it was giving, now they think its the fuel regulator sensor?

I'll guarntee you the O2 sensor was good. The flooding problem will be detected by the upstream O2 sensor, and that would set the code. There has to be 3 things to start an engine, spark, fuel, and compresssion. Has anyone started by looking at engine mechanical?

Don't get frustrated. Cars can be very difficult to work on at times, but they can all be fixed with patience, perseverence, and a diagnostic approach. If it's not firing, we can conclude that the spark is either insufficient, or a communication problem with the powertrain control module.

If they say they have checked everything, and still can't figure it out, it's time to try another shop, and not the cheapest one in town. How much money have you got invested in the last two shops?

Luckily only towing charges, they say if they cant find the problem they wont charge me, so I've been lucky. Would you suggest I take it to a master mechanic?

LET ME ASK YOU THIS. YOU THINK JUST A FUSE MIGHT BE OUT? OR DO YOU THINK IT'S ALOT MORE SERIOUS, SEE THIS PROBLEM ALL REALLY STARTED AFTER I HAD THE TRANSMISSION REPLACED, AND HAVE HAD THE FLYWHEEL HAS BEEN CHECKED OUT AND THATS NOT THE PROBLEM. THANKS!

I doubt it. There is a possibility this could be a whodunnit since the problem began with the transmission replacement. I would want to have the shop recheck their work and make sure this problem wasn't human induced.

Are you saying I should take it back to the Transmission shop? But that was like a year ago?And We tried to tell them that they caused it and they simply denied it. What do I do?

Wow, you've been putting up with this for a year? I would suggest to go ahead and find a good shop and agree to start with an hour of diagnosis time and see where that gets you. You may need to buy more time if they feel they are getting somewhere with a resolution to the problem.

You must ask lots of questions, have a good dialouge with the shop, and never let a stinking cat lay on the porch too long before you get it resolved.

Take the technician for a ride with you, reproducing the symptoms you described for the technician. Got to have everyone on the same page.

The whole thing is with the start up, it has nothing to do with the way the car runs.I would've figured that they would've been able to figure it out quicker since it is when the car tries to start up. But thanks!

Hi guys,

I have just been reading these posts and if I may I will add my 2 bob's worth, ok. As I see it the problem is hard to start tending to flood but when up and running is ok. So this is what I would be doing, start with cleaning or fitting new spark plugs, checking gaps are ok, or if iridiums fitted don't touch gaps, hook up fuel pressure gauge and key to start (don't crank) check rail pressure, is this ok? Have engine on an oscilloscope or a good quality scanner with ignition snap shot capability and attempt start check ignition KVa readings, my thoughts are that you are down on ignition voltage, you can also get an on car injection test done this will pick up leaking injectors, you can also get the exhaust gasses checked on a 5 gas analyzer, if the Hc's are up you may have an injector leaking, just a few thoughts to help you along a bit.

Well thank you so much for your two bob's worth, it makes sense. Check this out what the mechanic did to me today, (now keep in mind, my car has been at his shop for 1 1/2 weeks) he says, well if you give me $500.00 I will figure out what the problem is and have it fixed by friday. BUT he's been telling me all week he cant seem to figure out what is wrong with the car.I chunked his dumb ass $50.00 and told him to go find him another DUMBASS, cause I look at it like this. My car has been in his shop for a week and a half and he was supposed to be finding the problem, then he wants to say give me $500.00 and I will find the problem by friday.I was FURIOUS! I think he thought I was gonna be like oh ok do what u need to do. NOT!

G'Day,

well some operators are only after you hard earned $$$ and stuff the rest, with the information now at your disposal and a few tests that can be done quite easily, have a talk to a few work shops and see how you get on, I will keep watching.
