Replaced Crankshaft Position Sensor, now car cranks but won't start...

[loganbro28]

Before reading this post, check out my original post explaining my original diagnosis: https://shoforum.com/threads/uh-oh-...at-idle-92-sho-mtx.146552/page-2#post-1601922

So after getting the 211 code, I bought a replacement CPS from SHOsource, along with a new water pump and timing belt. A friend and I replaced everything, but when we went to fire it up. It only cranked.... no start.

Any thoughts? Did we somehow mess up the installation? Could the CPS have been faulty? Is the engine out of time? We are going to work on troubleshooting it again today. We did some other diagnostics that would be helpful clues but I can't remember exactly what we found, I will confer with my friend and follow up here.

#1 reason for a no start after a CPS install is a bad ground. Double check the ground on the back of the intake and double check the two bolts that hold the crossover tube to the intake. The DIS is grounded thru those two bolts.

well, we figured out the problem... hate to say it, but we put it on backward. It was cracked open and broken. Now is time to buy another CPS. The question is, which one to buy?

https://shosource.com/products/ols/products/crankshaft-position-sensor-89-95 sho source for $140

or rock auto for $18. not sure why shosource costs so much more... on rock auto it says its for a 3.0 DOHC but doesn't mention the SHO. however, there weren't any other 3.0 DOHC engines so I assume it must be for the SHO. Also, the photos seem to be identical.

The one on Rockauto is a new Chinese offering that just came on the market. That's why it's so cheap. It cost alot of money to get the SHO Source ones made. That's the difference. I have no experience with the new Rockauto ones but they look correct and if they function like they look then $18 is a bargain.

Let's us know if they work Chad.

The Rock Auto ones will probably start the car, but my concern would be longevity and how they will handle the heat. I have heard of no problems with the SHO Source ones.

The ones that SHO Source offers are the ones that Brian Morgan had made a few years ago. My guess is that the new Rockauto sensors are made by the same company. Probably stole his product from under him.

Thanks Chad, the ones investigated earlier (not the rock auto, i don’t have one of those) were exact copies of mine without a part number on the head like mine.
I didn’t test them of course. There are over 300 of mine out there. Failure rate of mine is around 1%. There was one diagnosed and confirmed bad after install.
I will sell my remaining inventory for $20 each plus shipping for anyone interested.

Make sure doing that didn't bend the vanes on the sprocket.

The Rockauto sensors arrived today. They look really well made and look to be a quality part but they are definitely cheaper Chinese sensors. No markings on them anywhere. The connectors look cheaper than the OE ones. I have no plans to use any of them right away but next time I need to use one I'll use one of these.

Is the length correct compared to the original ones, they look a little short

I have a few good used sensors on the shelf and several new in the box sensors and these match up pretty good to all the other ones that I have.

This is great timing because I'm getting a 211 and 214

Not that I noticed, but it was dark when I pulled my codes.
