No start
 

So I was driving in one of the mall of america parking ramps last night looking for a spot, and just as I'm pulling up, I noticed my car started running a little rough. I pushed the clutch in, it died, and now it won't start. I've got spark and I can hear the fuel pump running as the car is turning over, and can smell fuel in the engine bay. I'm stumped as to why it would be running just fine, die, and not start. Any suggestions?

Re: No start
 

Hows your timing?

Re: No start
 

ECU has new caps? Mine did some funky stuff, and wouldnt start half the time when my ecu crapped out.

Re: No start
 

The ecu caps have been replaced once already, but I dunno how long ago. The last time I checked the timing, it was spot on.

Re: No start
 

I would throw a spare ecu in if you have one, just to rule that out.

Re: No start
 

The only other ecu I have is a socketed eprom with no chip. I'm still waiting on the keydriver chip I ordered.

Re: No start
 

I have a kedriver chip I could sell you for cheap, let me know.

Re: No start
 

I just got the chip, threw it in the ecu, so I'll go throw that in and see if it does anything

Re: No start
 

Bring tools with to check the timing belt too.

Re: No start
 

The car is home now, I put the eprom in, still didn't fire. Checked the timing belt, it's just fine. I'm thinking the cam sensor probably took a shit. I was looking at it, and noticed a little bit of oil at the bottom of it.

Re: No start
 

Do a compression check next. Before you even start troubleshooting any further. Even if your engine is cold you will still get compression. My brothers car was doing something similar. We did a compression check and it was 60 accross the board. Redid the timing and the car was good to go.

Re: No start
 

Ok, The Compression test came out just fine, I don't have a timing light right now, so I can't test that just yet, Put in a new Eprom chip, and the damn thing still won't start. When I connected the new ecu, my logger connected to it just fine. After turning it over a few times, I turned the ignition off, checked a few things, then turned the car back on, and the logger wouldn't connect. The next thing I'm gonna try is getting a timing light, and replacing is the cam sensor. Anyone else have any suggestions?

Re: No start
 

Does it try to turn over.

if it does.

it die when you pushed the clutch in.
How new is your clutch/pressure plate.

Re: No start
 

It turns over just fine. Clutch disc only has a couple thousand miles, Pressure plate is unknown, but was in good condition when my new motor was built and worked just fine before the car died.

Re: No start
 

You say that you have fuel and you have spark and you have compression. Those are the 3 essential things your need, but if your a/f ratio is way off (due to say a bad coolant temp sensor) then it won't start. You said you can hook up your logger, can you check what your temp sensor is reading? those little bastards can go bad and cause a no start condition.

Re: No start
 

By saying to check the timing, we weren't talking about ignition timing. You need to check the timing belt timing to see if it is off. There is a good chance you jumped a few teeth on the belt.

Re: No start
 

I'll double check the timing belt timing if it's not raining tomorrow. The logger connected the first time I tried it with the eprom, but after then it wouldn't connect. So unless it decides it doesn't wanna be a bitch anymore, I can't do too much with that.

Re: No start
 

Your logger won't connect? Hmmm... and you know for sure the new ECU you put in was a known good ECU?

Re: No start
 

I had this problem from time to time with my 2G where moisture would get into the MAFT box and it would basically not work at all. Try hooking up a standard MAS and see what happens.

Re: No start
 

My MAFT box is inside the car, so I dunno how it could have gotten moisture in it. The ecu I got came from a running car (or so I was told). Brandon, what you said about the coolant temp sensor seems like it might be right, When I turn it over, een if it's just for a couple seconds, the plugs are prety wet. So that leads me to believe it's either dumping in way too much fuel, or there's just not enough spark to ignite it (weak coil).

Re: No start
 

do you run ur logger everytime you drive

Re: No start
 

I got the chance to look at a few things today. I replaced the coolant temp sensor, checked the cam timing, and that was perfect, re-checked the ignition timing, and that was perfect. When I first tried starting it after relacing the coolant temp sensor, it fired a few times, but not enough to start. After that, it didnt fire at all. I messed with the settings on my translator box, but to no avail. I tried both the stock, and chipped eprom ecu, adjusting the translator box accordingly, but still no start. One thing I noticed, is that after the first time I tried starting it, I could smell fuel right away, so could that possibly mean it's somehow getting way too much fuel? Is there anything besides the ecu that controls the injectors?

Re: No start
 

This actually sound like what happen to me. Recheck the coolant sensor wiring. My sensor was fine but the wires to the sensor were like plastic, probably because of the heat. Redid the connections and fired right over. If you get your logger to work check to see what it reads. when it was disconnected it read like -76 or something. I am still guessing that is the problem especially if you are getting spark and smell fuel. Mine ran rich... smelled heavy fuel inside the car... and once in a while fired...

Re: No start
 

fuel pressure too high (plugged return hose), leaky injectors or grounded injectors.

Re: No start
 

Your logger still wont connect to the ECU?

Re: No start
 

Still won't connect. Anyone have a spare wire I could borrow to make sure mine isn't bad?

Re: No start
 

I know Steve Hill has one, because I gave him my old one.

Re: No start
 

check your alarm system. rember last time it would not work right when it was unpluged sence the dumb ass messed it up putting it in

Re: No start
 

You have a GM Maft right? I would throw the stock mas back in and see if maybe that took a crap...

Re: No start
 

I don't have the stock mas anymore, that got sold about a month ago. I'll spend some time this weekend taking out that shitty alarm system and see if that fixes it.

Re: No start
 

Fuel injector stuck open? Have you tried putting your foot to the floor when trying to start it? This will shut the injectors off and clear it out if you are too rich.

Re: No start
 

I figured out what it was, and it's something I should have checked right away. Turns out it was the fuel pressure regulator. I unplugged the vaccuum line, it started, and started pissing out fuel like a firehose. I ordered a new one today.
