Hey anyone out there...FIRST OF ALL! I did search MPFI on search and didnt get the answers I needed so PLEASE HELP!!!
I have a 1991 Honda Civic DX sedan and I did the MPFI conversion 2 days ago and I am not the best at wiring so I guess you could say I second guessed myself on the wiring. I followed the instructions to the T and as far as depinning I only depinned that one wire because there was already one at the other location. Anyway, I got everything done, and I know at least 3 injectors are firing because when i first got done and tryed to start gas was shooting out from 3 injectors and so i got the O-Ring set and now they dont leak. Anyway, my question is, when I try to start it, it just keeps tryin to start and turning over but never catches. What kind of things should I look at? Thank you so much for your help in advance as this is my daily driver and I had to catch the bus to work this morning! ANY INFORMATION WOULD BE OF HELP!!!

Eh, I'll just talk to my painter about that one then
I was under the impression that Syncromesh was a heavier-weighted oil? Dunno, something about hiding problems and thinner oil doesn't make sense to me haha. </TD></TR></TABLE>
haha, now that you say that, it doesnt make much sense to me neither, but it goes down my funnel quicker than MTF and it tends to leak out more...or did with my old LS tranny.

yes
yes
anybody have a pic. or link to the back of an obd1 b-series showing the sensor location and wiring? i did the obd0 to obd1 conversion and i need to know what wires go to the IACV, water temp sensor, knock sensor. I believe the knock sensor only uses 1 wire

actually no, spin it (assuming your speaking of bearing type tensioner) if it feels pretty tight and smooth. its good...tensioners dont go bad in 90K miles..if the engine is going on its second or more t-belt i would replace all seals and tensioner..

if u have the obd-1 jumper conversion harness it provides the 4 wires you need in order to run the o2 sensor
everything else pretty much stays the same as far as sensor from what I remember
you can use most of all the same plugs except for the distributor, o2 sensor, add knock sensor and injector plugs

214 for front pair.

370 for whole set

thanks for the heads up on the tensioner. im going to call dchautomotive (temecula,ca) and see if they can give me a good deal on one. i bought the timing belt kit from them, but it didnt include a tensioner.

Really looking for something cheaper. I wasn't expecting to invest in suspension yet but I got a killer deal on some springs and recently came up on BNIB rear illuminas for $150 shipped. If I could get a deal on some front shocks, I'd be in business but not looking to spend an arm either... it's only a beater

I have the jumper harness too. The o2 is on a seperate harness from Rywire. What I didn't know until today is that you need a different plug for the water temp sensor on obd1. I got it figured out now. Knock sensor is the same wire.

WE might do ebay... but i doubt it.
PM me ASAP with the parts you need and the make, model of the car/motor.
i'll work on pricing first thing in the morning when i get to the office.
you can get quotes from DCH, i'll meet or beat their pricing on most items.
