so i just had my engine rebuilt due to a bad rod bearing - - New rings, honed cylinders, all new seals and bearings, and valve job. I got done dropping it back in and bolting everything on... but NO START!!!! [sm=wtf.gif]. It cranks just fine, it is getting fuel and spark to the cylinders. I've checked and re-checked and re-re-checked all wires, harnesses, grounds and everything is as it should be. IM LOST!!!

I've also replaced the crank and cam sensors. Pushing gas pedal down does nothing so i know its not an IAC problem. At first it didnt even sputter, it would just crank and crank. Did a compression check and all cylinders on passenger side are about 150-160. Drivers side were ALL abou 90-100@@@ WTF!?!? Poured a little oil in those cylinders and compression got up to 150 and would sputter a bit at start, but still wouldnt catch.

WHAT DOES THIS MEAN!!!?? I'm about ready to take a sledge hammer to this thing.

go over all of your sensors again. i just started my 302 stroker tonight, and i had the same problem. turned out that the crank sensor wasn't fully plugged in. later on i went to start it and it wouldn't start again. that turned out that the maf sensor wasn't fully plugged in. also if you were giving it gas, it may be flooded. pull out a coil pack, pull out the spark plug and see if it's soaked in gas. put it back in, put your coil back in, connect your sensor. hold your gas pedal to the floor (this disables your injectors) and start it. when you hear it wanting to start, let your foot off the gas. that's what i had to do. hopefully it helps you out. keep us posted.

+1 on checking your CKP. Mine wasn't all of the way in after I put my engine back in and I was looking around for a reason why it wouldn't start, too. Good luck.

How sure are you on the driver side timing? Did you remove the cam gears? Did you remember to put the crank trigger on?

jsmarsh25 his car is fuel injected he cant flood it by touching the gas peddal only by having to much fuel pressure or to big of injectors.

I'm not sure of either of those because I had a local engine shop do the rebuild.I replaced the crank andcam sensors only after it wouldnt start thefirst time, so i know they are both seated properly, and i've pretty much un-plugged and re-plugged every sensor multiple times. I was a little suspicious of the crank trigger though,maybe they put it on backwards?Although the lowcompression on all driver-side cylindersis throwing me. Is there any easy way to check the timing on that side?

pete1665

so after checking everything including fuel pressure (which was perfect), i did a compression test.

-Every cylinder on the passenger side was about 150psi
-Every Cylinder on the driver side was abou 90-100psi!!!

If the timing was off because of notsetting it up properly when installing the chains, would that cause low compression, or would it be something more serious? Also, should it be around 180psi, or is 150 ok?
