help with crank position sensor

[loudnproud]

Ok so I just bought a first gen eclipse.lets just say I got screwed . Any way my block has a crank I bought a second gen eclipse block today. There is a crank position sensor plain as day on the second gen well I'm mating a first gen head on this block so does the first gen harness have this sensor cause I never unpluged one spool wtf do I do do I block it off keep it unpluged I am so confused ore sure it will run without this plugged in considering my original didn't and is there anything I need to get special to mate the two together

The first gen and second gen motors have completely different crankshaft position sensors. If you have a 1st gen car nd harness and your using ## 1st gen head just use that one and don't worry about the one on the block you can just leave it alone.

Are you talking about crank or cam?

 

[loudnproud]

Talking about the crank ok so can I just remove the sensor or just leave it sit. I'm worried that its going to get caught in the timing belt and yes I'm running a first gen head so I can just run the cam sensor because these blocks are almost identical its so weird I mean other than upgraded lines like oil and coolant I think I'm going to run steel braided lines looks a lot better and I can remove the crappy clamp type things holding them in

You need to have crank signal to ecm. You can't just disconnect that sensor.

I didnt know the 1g had a crank sensor. The 2g yes but im pretty sure the 1g gets both its signals from the cam sensor on a 1g.

Oh and a 2g motor will not mount into a 1g. The block does NOT have the mounting points as a 1g. The 2g has mounts on the trans not the block.

This has been beaten to death many times. SEARCH

...the 1g gets both its signals from the cam sensor on a 1g.

This is correct. So you can either remove or leave disconnected the 2g crank position sensor.

Ok well next prov how the heck do I mount the engine then

 

[Boost_freak_87]

A 2g short block will not work in a 1g. Try finding a good working 1g block.

Ok well next prov how the heck do I mount the engine then

sol #1: find a good fabricator..Prob cost more than the worth.
sol #2: Find a good 1g block...Prob easiest method
sol #3: Find a 2g car to go with the block then you can use the combo..Prob not as
good as sol #2.

Is there any difference with the two types of 1 gen cam,crank sensor

 

[madmstr]

There are two types of 1g sensor. one with a pigtail coming from the bottom , the later ones came with a connector with a metal clip out the top.

2G blocks do not have the front and rear roll stop mount provision on them. You can use a 1G engine in a 2G, but not the other way around.


Worst-case scenario...find a good non-turbo 1G engine in the junkyard and use the block and crank from the non-turbo engine on your turbo car. You definitely need a 1G engine, though.

Being a '93, does your car still have the factory-installed 7-bolt or did someone swap it to a 6-bolt?

The OPs post was almost 2 years ago, I hope he already got it figured out by now.

There are actually 3 , The Black top, the Green top, and the Green top with the pigtail. The Black top is the preferred CAS but any of them will work.
