Could be a bad sensor Could also be a mechanical issue Timing Chain or Belt problem DO NOT throw parts at it How do you like that code reader? I'm thinking about an Innova 31603 I have professional scan tool software, but takes time to set up, to just get a quick code check & look at I/M Monitors

First I will check the fuel pump by opening the gas door then put ignition on the on position, listen for a hissing noise. if you don't hear nothing it could that your fuel pump is no good. Next I would check relays, then I would go to the fuel pressure line to see if you got pressure. try that Could also be clogged injectors, even if you have a vacuum leak will also cause that problem. So, it can be a few things. Good luck.

Suggestions: loose/corroded connection between the fuel pump and the computer; short between the fuel pump and computer; computer firmware needs to be reset.

More then likely you have a bad door ajar switch, without a scan tool, you can not tell which one, but thats the moat likely cause, when your alarm is on and it goes off for no reason the computer is seeing the door switch change from closed to open, thinking door is open it sets alarm.

It is only necessary to post your question ONCE. See my previous answer.

Either your solenoid is sticking or your key switch is bad. Test by disconnecting the positive line to the starter (cover the connector with electrical tape to be sure it doesn't contact the chassis), then test for voltage at the S connector on the solenoid. If there is no voltage at the S connector with the key ON (not just when it is moved to START), replace the solenoid. If there is voltage at the S connector with the just the key ON, your ignition switch has failed and needs to be replaced.

Do you have spark to the plugs and are the injectors working ?

Disconnect negative battery terminal for a few minutes. Or purchase an OBDII reader to help clear the codes.

get a code reader that can erase dtc or go to parts house

Check to see if your filler pipe is rusted(The pipe where you put gas in). Do you smell gas stronger when you fill up your tank?
