5sfe wont crank over... - Toyota Nation Forum : Toyota Car and Truck Forums

The battery is putting out plenty enough power, however, the motor wont turn over.

Since it is pouring down here i havent had much time to look at it yet. I pulled out the 4 tubes that lead down to the spark plugs (from the dizzy) and the one closest to the battery was covered in oil... (im not sure if this is usual, relevant, etc).

I guess i need to do a compression check, and see if i have fuel squirting, and a spark... So here enlies my question..

How do i check for fuel pressure??? The injectors are behind the throttle body so do i just pul and try to crank it over and watch for a fountain of fuel to spill out?

and... when checking for a spark, I just pull out the plugs, and crank and watch for a spark, correct?

i pulled the plugs, one plug was messy with oil...

But no spark, i went up to autozone and picked up a new coil pack ($46) and installed it, and still had no spark afterward. UGH.... so frustrating. What do you guys think... could it be an ecu problem?

if the engine is not turning, then i don't see how fuel pressure or spark could be the cause. are you sure it won't crank over? or do you mean that it won't start? two totally different things.

i mean everything is spinning, but the plugs arent sparking.... I tore apart the dizzy today, and it was a bitch. I put everything back together meticoulusly... and still nothing.

Suggest you download the ignition info from the Toyota service manual at the link below.

There is a very good troubleshooting proceedure.

Figure out what is causing the lack of spark before doing other tests such as compression, etc.

i know this can be a stupid quesiton, but did you ground the spark plug when you checked to see if it sparked? without it grounded, it wont spark.

vsixcamry · 07-20-2007, 02:25 PM

i set it on the valve cover... that means it is grounded right? or does the valve cover not conduct?

thanks for the help guys ill get to work on it shortly, and thank you jeeves once again for posting up a TSRM to save my ass.

welll i replaced the igniter today, and still wont start... I am thinking its a problem with the computer... which really pisses me off.

10 amp start fuse?

You'll save yourself a lot of time and money by eliminating guess work. Diagnose it or have someone diagnose it. Did you check to see if the timing belt is broken. A broken tbelt would sound pretty obvious when you crank it over (because there's no compression.)

vsixcamry · 07-22-2007, 03:06 PM

timing belt is good, the cams are turning. and yeah i checked the fuse its good too...

ghettosled · 07-23-2007, 07:10 AM

the valve cover might not be grounded because of the gaskets on its mating surfaces. find a good ground on the engine block or body to make sure.

^ i did still no spark.

I got tired of trying, now its gonna have to be big money out of my pocket. I hate mechanics touching my car but i decided to let them anyway.

I got a call this morning saying something had happened electronically. They gave me new distributer housing redid a wiring harness, and a fuse had been blown somewhere along the line. They put in new wires/plugs and had to even drop in a new ecu. PAIN IN THE ASS... It cost me $517, which i guess isnt bad but still another barrier holding me back from working on my supra.....
