Ok well I just replaced the female side of the speed and ref sensors and if youve been reading my threads I just replace the actual sensors. I could get my car started but it would sputter and then die. Now that I replaced the Female side using shielded wire and solder and new connectors, I cant even get the car to fire.

I checked for spark by pulling a plug off the spark plug and putting it on the intake manifold. When cranking I do not see anything. No spark.

Can anyone in the San Antonio area come and help me out. Also how can I check for ohm reading on the female side of the speed and ref sensors?? I want to make sure the wire isnt shorting out or something. A link or some in depth detail on how to do it would be nice because Im a noob.

Anyone

Did you try the fuel relay yet? How's your tach while cranking? I'm having a no start problem myself but hopefully yours goes better than mine has.

Ive tried replacing the fuel relay to a new one with no luck, I havnt actually jumpered the fuel relay yet, My tach does move a little bit, maybe 1 cm or 2.......

as in the needle doesnt even get to the first line?

BlacknRedGT

It doesnt get to the 1 for sure... I would have to go check to see if it hits any line

Well, not sure I can help you much. Mine just barely shakes and i've replaced a lot of different things. I hope your situation resolves much quicker than mine

BlacknRedGT

ya. mine just shakes a little bit too. I dont have a oscilloscope to check if its actually getting above whatever voltage. Anyone know how much one of these costs and where to get them?

sputters and dies? almost sounds like ain aiflow metering problem. have you checked your intercooler pipes?

BlacknRedGT

it did sputter and die but now it doesnt even start... What do you mean by air metering problem??? The intercooler pipes look fine to me.

did you check for spark from the coil. If you get spark there (but not the plugs) then maybe it is a bad cap or rotor, Can you hear the injectors click when you turn it over? Use a test light if your not sure.

Does your car have an alarm? if so, look at clarks garage and take the alarm relay out and jump it. My sons car was doing the same thing and it turned out to be a bad alarm module. Jumped around it and problem solved. hope that helps...

BlacknRedGT

Ill try both of those.... Anyone in the SA area that can help me though??? or know where to get the osiclloscope from?

dme

Keep it simple. There is plenty you can do without a scope. The reason the air metering system was mentioned is that when the connector to the air meter (connection at the air box) is disconnected, the car will sputter at startup and die if you hit the gas. If it isn't running at all then finish the check for spark and verify that the injectors are running. That will help determine which direction to continue the search.

ok well I tried a few things but had to stop before the big game.. Can anyone verify the female side of the wires on the speed and ref sensors: 1= Brown wire , 2 = white wire, 3 = Black... I know a few of you have changed the female connectors. I jumpered the dme relay to make sure the fuel pump was on but that didnt work. Havnt tried bypassing the alarm yet but Its started before plenty of times so I dont think that would be it. How exactly do I check the injector wires and spark at the coil?? I dont have a testing light or anything. ohhhh.. and I soldered every wire on the speed and ref sensors female side so everything should be good.
