no start 1g
 

Bought a 93 laser with bent valves. So I replaced the head. I have spark, fuel, compression 150 all the way across and timing is dead on. I just replaced the ecu as well.

I got the car running 4 days ago and it ran for about 5 seconds then slowly idled down and killed and it would do it over and over. when I went to try to start it this morning it won't start at all. still has fuel,spark compression and timing is still dead on..


Someone please help me!!!

i got a case of beer for the first person to come figure it out :)

Re: no start 1g
 

is the coolant temp sensor unplugged or broken?

Re: no start 1g
 

plug is broken but i have it wired up to the sensor

Re: no start 1g
 

if that connection isn't great the car wont start

Re: no start 1g
 

ok i will go recheck it now

Re: no start 1g
 

Agree'd check that connection. Also check the CAS plug, and ensure the CAS itself is installed correctly (not 180* out).

Re: no start 1g
 

the one connection seemed a little loose so i crimped it down more and it attempted to fire.. but still nothing

Re: no start 1g
 

cas is good tested it on a buddys car and its putting out spark

Re: no start 1g
 

Check fuel psi at the rail

Re: no start 1g
 

I'm not implying it's bad, i'm saying ensure it's connected fully, and ensure that when you installed it on your car, you did so correctly because it's easy to accidentally install it 180* out.

Other thoughts:

Massive vacuum leak
Verify all 4 plugs are sparking (maybe you have a bad coil, only running on 2 cylinders)
Base ignition timing (center the CAS in the slotted holes to start with)
BISS screw improperly adjusted
MAS bad or unplugged

Do you have a logger, or link, to look at some of these signals?

Re: no start 1g
 

im buying a logger today hopefully and there is spark on all 4.. i will check the others

Re: no start 1g
 

Ive started my car, both with a bad ECT sensor and a maf that is unplugged. Make sure to check for a bad and weak coil pack as well. You said you verified spark? And how do you know youre getting fuel? Pulled the plugs and smelled them or lf they are wet? Check youre fancy relay under the the radio as well. Ive ran in just about every no start condition there is on these darn things...sometimes its really simple other times it could be intermittent...also I did not hear you mention you checked your main block fuses check those as well.

Vacuum leak mixed with a bad maf.. Got it running thanks guys :)

Re: no start 1g
 

So i got the car running and drove it a couple times around the block. Let it sit for a couple days cause i have been busy with work, and now it wont start again. Has fuel spark compression and timing is on..... Any other suggestions ?
