My truck won't start!

i have a 2003 tacoma with the trd supercharged 3.4... drivin it one day and all the sudden it died. its been at toyota since then and they cant figure it out. changed the fuel pump, IAC. mass air, cam position, and throttle position sensor... any ideas? it has fuel, spark and air. why wont it start?

 

Have all the gaskets been inspected?? If you lost a gasket anywhere in the engine it could prevent the engine from building compression.
Have they inspected the ECU?? If it ran out of capability to manage the new AFR it could have fail safed itself...Maybe?? Chris??

 

Wouldnt something like this throw a code?

 

i have yet to pull the engine apart. the cylinders are still building compression but i dont know about the other gaskets. its funny because i was going to buy another computer but then toyota can get one in the united states. they have to b\rebuild mine. what do you mean it ran out of capability to manage the new afr? and do you know me?

 

they cant get one in the united states*^

 

I would think so- but ::shrug:: the Toyo techs should have all the "normal" stuff checked already.
I'm going out of the box.

I had problems running a blower on a Dodge cause it would take out the intake plenum gasket with vacc and the engine would run horrible....Not sure what else could happen....but I'm sure there is something.
If the ECU can't balance the AFR then maybe it shut it self off...or maybe it melted a wire somewhere...or maybe a fuse...IDK

Just throwing ideas out.

I don't- Chris4x4 is our resident Forced Induction and Tacos guy.

 

ya the tech is kinda lost... it seems to be wiring or a sensor but idk... i hope its not the ecu. i cheaked all the fuses and the wiring haarness was checked from the front to back and there seems to be no breaks.. the guy i bought this truck off of lives in pensicola florida and he works for the coast guard.... i though you were him there for a minute.

 

toyota is 80 bucks an hour for service and it has been there for a few weeks! i just want them to figure out the damn problem. you think toyota would be able to figure out their own shit.

 

couple more days and the insurance might just total it. if you got spark, gas, air it should atleast do something. even if it sputters. start with the basics. its always the simple shit that bites you in the ass. same way with aircraft. get so involved in a problem that you overlook the obvious and find a breaker/fuse poped. check the grounding strap for the engine maybe it got broke and the engine doesnt have a good ground there for not sparking good.

 

So what's the latest?

 

A mechanic who cant get an engine started and/or diagnose why it cant start within one hour isn't worth spit!

Fuel & compression & spark. If they are there the engine has no choice but to start. It may or may not run well, it may or may not stall, etc., but it aint rocket science.

 

junk computer..... the guy at toyota couldnt even figure that one out....

 

So after it's all said and done, how much did it cost to get fixed?

 

well i went to get my truck and they wanted 1300 bucks for nothing and i didnt pay it. i have my own wrecker company so i just took it and told them i wasnt payin for something they didnt do... i have a computer on the way from california out of a wrecked truck for 350... see if it fixes it i guess...

 

That's pretty cool, so they just let you go back there and get your truck then? Didn't cause any problems?

 

no not really i told them it was bull**** that they cant even fix it and i waisted 2 weeks having it sit there... it was still inside and they were still working on it and i told them to put it back together and push it out..

 

So who decided it was a junked computer?
