Only starts when towed 93 manual

[tgreene92]

just to make sure, have you checked for spark, could not be getting it on enough or all cylinders, sounds stupid but i didnt see it mentioned anywhere.

 

[tgreene92]

and if you havent already fix your EGR just to make sure thats not causing a possible string of problems, and if your concerned you ripped a wire or something your EGR is where itd be, ive done that a few times, idk why there i dont seem to rip wires anywhere else just at the EGR.

So, it stays running as long as you keep the rpm up? Have you tried to start it while giving it a "little gas"? (Holding the throttle open a little) If it starts like that, change your IAC. I suppose the min idle speed screw could have backed off, but don't mess with that, except as a last resort.

That could be the case on start up but when running it runs excellent. It all just points to the computer telling the injectors to not fire.

Yup tried that too. No start.

I have not fixed the EGR yet. Yeah I did that on my 4runner haha

does it still start when towed, i dont see how towing it would make any difference with the injectors firing. the only reason a tow should help start a manual car is if the starter is bad and cant spin the flywheel, towing it will spin the fly wheel and then when you turn the key and give it gas and spark the truck starts. theres a very similar thread around here somewhere about injectors not firing if i can find it ill post it. have you considered that your flywheel could be cracked or broken, starter would still crank but not engage the flywheel. i know this doesnt really fit your original symptoms but just throwing it out there,you could have damaged it towing it home.

Well the starter works, it turns the flywheel, and with starting fluid the engine will fire and run for a little bit.

The other day I towed it, it takes a few seconds in gear to get the thing to start. It will actually come down to idle speed for a few seconds and then die, almost like when you unplug the MAF or something. I appreciate all your guys help so far. This is a tricky problem

 

[tgreene92]

yea it is, have you checked all related grounds. thats about the only thing i can think of right now before you go swapping computers.

 

[FIND]

checked compression and the condition of your plugs?

 

[tgreene92]

a compression issue could be the problem but still wouldnt neccesarily keep it from starting, but like he said before it runs great when it does start.

 

[FIND]

shoot, I didn't notice it ran good when it actually starts.

 

[2strokenut]

Wow I've been wiped out by these druuuuugggs. Anywho, I changed the plugs and wires a few weeks ago. I also already swapped computers. My computer is fine. The search continues...

 

[tgreene92]

so your still having the same issue, crank and no start, have you checked for spark yet, i know i already asked but i dont think i got a solid answer. also have you checked the condition of your injectors they could be fried to the point that they wont fire. im stumped, if your getting fuel at the fuel rail and spark that does pretty much leave the injectors, could be some weird totally un thought of issue. if you havent already try covering the EGR while cranking, or just replace it since it needs to be anyway, i still think the bad EGR could be throwing something else out of whack preventing a start. when was the last time you had it pop started? may want to do it again just to make sure it still does start.

211- (M) Ignition PIP signal was erratic or missing - Ignition Systems

???

211 is the no start, cant cid cylinder #1 to start the vehicle, which is why at a certain rpm it runs.

 

[OneLever]

cant id cylinder #1

x2

What were the results of your crankshaft position sensor tests? Is there gunk all over the crankshaft pulley?

I suspect an intermittent ground to the crankshaft position sensor through a tear in the harness insulation. Can be tested by wiggling the harness while it's running with something to keep your hands out of reach of moving parts.

I'm not immediately familiar with the camshaft position sensor equivalent to your year. But the same principle could cause this perhaps.

More specific? haha

Haven't been able to yet its just been sitting at my buddies house. He is going to test the crank sensor monday and see what happens

so your still having the same issue, crank and no start, have you checked for spark yet, i know i already asked but i dont think i got a solid answer. also have you checked the condition of your injectors they could be fried to the point that they wont fire. im stumped, if your getting fuel at the fuel rail and spark that does pretty much leave the injectors, could be some weird totally un thought of issue. if you havent already try covering the EGR while cranking, or just replace it since it needs to be anyway, i still think the bad EGR could be throwing something else out of whack preventing a start. when was the last time you had it pop started? may want to do it again just to make sure it still does start.

If you spray starter fluid in and it will fire. Might try to push start it again and see how well it runs. I still can't do much with my knees and all

the starter fluid just falls to every cylinder, so it bypasses the injectors, so with that said, since the car cannot id cylinder #1 to to start, it does not know what piston is where, and cant match fuel injectors to spark. starting fluid just skips that since each cylinder will have it in it.

 

[corkey]

almost a month now

did it start yet ?

Ohh ok gotcha. So, what does that mean? What is causing it to not ID the number 1 cylinder? Crank sensor malfunctioning not allowing it to id cyl #1?

Nope.
