well the car wont start. it worked about two weeks ago. but now the car wont start. its weird there is no spark.

any ideas what could be wrong?

Is it cranking and just not turning over due to a lack of spark?

If so, I'd check everything in the electrical path from your battery to your plugs (coil pack, wires, the plugs themselves, etc).

Are you sure that no spark is your problem? (are you getting gas, etc)

More info pleassseeeee!

its cranking, just no spark.

new batt, checkec coil. plugs are great. checked fueses. ecu gets power, it gets gas.

it just stoped working one day.

How about your spark plug wires? Are they in good condition? Not grounding to the block before the current reaches the plug or anything?

I don't know what to tell you man, I'm a relative newbie so I can't really think of anything else

Good luck!

Crank Position Sender

oh i forgot to say. i saw some kind of liquid in in number 1 spark plug hole. do u think it could of shorted out something?

Where is the crank position sender? is that the one in the middle front of the engine?

Yes, and Im trying to remember how to test it. I suppose it should throw a code first of all.

the CEL is on when i put it on the ON position.

u think it could be saying that its broken or something.

You need to read the codes.

Replace those autolites and the old plugs. It should fire up then.

Those plug wires are maybe 80 miles old. But as THAWA sais, they're crappy autolites.

Dont know what to say other than that... it has never given me any problems except for when the ABS computer ran the battery dead a few times.

With the cam and crank angle sensors, the ECU will throw a code if one's working and the other isn't. So, yeah, it'd be worth checking to look for codes.

Have you read through the FSM's guide to troubleshooting engine starting failure? It starts on page 178 of the engine & wiring manual Josh posted.

Blah, Ive run so many sets of autolite wires. There shit, but they all are(including Bosch & NGK IMO) and whats the likelyhood of all four going bad at the same time. Same with the plugs? Its a CPS, or coilpak. Im sure there are testing procedures for both in the factory manuell.

ok the car throws 3 codes
13, 23, 49

Clear the codes, try to start again, and then pull the codes.

Which MAF sensor do you have on your car?

the codes were cleared the battery was off for 2 days.

the MAF is the one in the car when i got it. maybe i didnt plug it in all the way i'll check tommorow.

Yay i got it to work. the wire for the cam angle sensor was completly cut so it wasnt getting a signal. so i put it back together and it started right up hehe. thx for you help guys!!!
