I just bought a 90 Civic Dx with a b16a motor (1st gen I believe since its running an OBDO pr3 ecu) and it has a problem starting

The first 2 tries itll pretty much just keep cranking, then maybe it will kick over run for 1/2 second then die, try again and itll run for 4 seconds, rumble then die, and again til it finally stays running on maybe the 6-10th try

Also if it does start running for a second and I touch the gas, itll kill it instantly

I havent had time to diagnose or really go over anything mechanical on the car yet But Im hoping this is an easy fix as I want the car to be my daily driver after I get finished with the body work in a few days

The only thing I noticed that is definetely wrong. There is a sensor on the left side of the head (passenger side) under the distributor and closest the the front of the car. Its a gold fitting screwing into the block, probably supposed to have wires connected to it (theres a few wires by the tranny taped together that I think dont lead anywhere). So I dont know what that sensor is yet but that could be causing it I suppose


The car doesnt have a tach so I dont know what RPM im revving to and Ive never had a Vtec motor before but I dont think vtec is working either. The car has a bad wheel bearing that I need to get fixed before I really beat on it.

Im hoping I can still pass emissions
Any help is appreciated

Thanks for any help

 

 

currently workin on an OBD0 B16 swap in my buddys CRX, that gold prong u speak of needs to be wired up. there is a single white wire that should go to it......................ill let u know for sure by tonight. (gota help him put his axles in) Ill look at it closely and let u know.

 

I have a loose red/white and green/white

How I would reconnect it I dunno, its ripped out right from the connection

 

I TRIED to check TPS voltage but was unsucessful

I used the middle red wire to take my reading from (pretty sure thats right) and with the ignition kicked over I wasnt getting any reading, had a beautiful piece of spliced wire to touch but no reading, so I turned the car ON and took a reading and was getting fluxuating results that were just kinda scatterred

So whats up with that

 

the sensor close to your distiributor needs to be wired up, but itsn't going to cause the problems you have. make sure you dont have your tps plug swapped with your evap purge. they use the same plug and the wiring will generally reach.

happened to me

 

also check your firing order

 

Well the car does run and runs rather well once it gets going

So I dont think I would have any swapped sensors now would I?

The tps does seem to be reaching all the way over from the dirvers side of the intake manifold though, unlike my d16a6 where it comes out of the harness at the passenger side of the intake manifold.

Could it be swapped with something else in the bay? or would the car not run at all then?

 

 

i checked on that sensor.....................i belive its water temp..........?

 

need more info on starting trouble
