Need help

[a/cwizard]

My vx has been sitting for 6 months and now wont start.jumped fuel pump relay and got fuel to rail,sprayed either and got fire just not starting on own.Drained gas out of tank and installed new gas.Vx just turns over.Could injectors be clogged from ethanol?Anybody know a dealer in houston that can put it on a computer and ck injector pulse and so on?

Yup, it sure does!!! Just like on marine watercraft; you tether a cord to the kill switch and the other end around your wrist, so if you get ejected from the seat then the rip-cord activates the kill switch.

It could be lotsa stuff. Here's an Isuzu tech video I have for a hard start or no start condition.

It's a RM file and you might need a RealPlayer to view it.

Clogged injectors unlikely IMHO. Not after sitting for just 6 mo in a hot dry Texas environment. Ethanol will absorb water and the mixture will eventually settle out to the bottom of the tank, but good gasoline has enough detergent to break it up and clean that out. Injector cleaners and additives such as HEET will also pretty much eliminate the theory. Esp since you have drained the tank.

Historically the bane of VX fuel probs has been the Fuel Pressure Reguator, but do not ignore air delivery as well such as cleaning the Mass Airflow Sensor, and checking the Throttle Position Sensor. Clean your PCV and check your EGR. I'm assuming that spark delivery is not an issue as you stated you got it to fire with ether.

Buy, borrow, or otherwise obtain a decent OBDII reader to see if the ECU is throwing any diagnostic codes, or has any codes in its history that may point you in the right direction. Your local Autozone or Pepboys or other major auto parts chain will often read those codes for you free of charge. My local stores will also loan out the tool with a suitable deposit if you cannot get the car to their store. They will NOT however tell you what to buy to fix it. They are not mechanics, and frankly I wouldn't trust them to be. Of course I'm not a mechanic either, this is all automobiles 101 stuff.
