I swapped my H22 from my 93 EX to my 92 VX. Installation and everything went well.

Both cars were running before the project started.

Little problem, however, I recently bought a Walbro 255 lph fuel pump for 92-00 Civic, installed it very easily, harness plugged in and everything.

Then installed the H22, and now the car will not start. I have a B&M FPR and B&M fuel pressure gauge, and I have no fuel pressure at all. The H22 ran flawless in the coupe with zero problems at all.

We checked all fuses, and I also switched the VX main relay to the EX relay just to make sure it wasn't the main relay (at which both click when trying to start the car).

When I put the key onto the ON switch, the fuel pump does not click.

I have also put the stock fuel pump/bracket on the fuel pump from the EX (which I know works) into the VX (gave the vx fuel pump to a friend) and still the same result -- no sound from fuel pump and no fuel pressure.

Any suggestions?

I need to have the car up and running tomorrow for racing. Any help would be much appreciated.

TIA.

bizump for daytime.

Try the stock FPR.

Thanks for the input, but I also used the B&M fpr flawless on the coupe before transferring. I'm thinking it's a wiring issue and still trying to figure out what the deal is.

Spade

As a temp thing you could trying running new wires.

1 is a ground check that one first.

Will do. I was just checking the whole helms diagram as well.

thanks.

Wouldn't use the stock fuel regulator and that fuel pump. Unless you have another way of controling the fuel.

I'm using B&M fpr and fuel gauge.

Is the pinout different for the fuel pump on the ecu?

I know my comment was in ref to the person suggesting you go back to the stock fuel pressure regulator

Ohh, ok.

I was checking with the Helms and looks like there is an electrical problem.

Here's a screen shot of the page for the fuel pump troubleshooting:



I disconnected the main relay connector. And with a continuity light I tested between the BLK terminal and the body ground (to the door) and had no continuity.

Made sure there was a good ground by testing at the fuse box and the continutiy light lit up.

When saying no continuity at the BLK terminal, says "Repair open in BLK wire between main relay and G101."

All I can say is whoosh on that statement. I'm trying to trace back to see if there is any disconnected harnesses.

Thanks for the help thus far.

It has to be a wiring problem if it is not even coming on. Just keep at it!

Some walbros are know for failure from the jump. I would check the pump for continuity as well so at least you know it is in fact working. If not then bang on it a couple of times and see if that solves your problem.

I too had a faulty walbro that I had to return because it would work when it felt like, even if i was driving down the highway, instant shut-off-ness..

I thought the same thing, but he said he installed a stock pump and still couldn't get it to start.

i love rice

check all your grounds. the same thing happened to me. the grounds are very important

poison

Thanks guys for the input...

Some definite strange *** things are happening.

When I first installed the H22, it ran for 10 seconds then died. I am thinking it just ate up the rest of the fuel in the lines with the fuel pressure going to 0..


The fuel pump will not make ANY noise at all when I put it on the ON switch, yet, at the main relay (with the relay plugged in), I jumped the Yel/Grn wire to the Yel/Wht wire, had a tiny spark when touching it , and the fuel pressure went from 0-40 PSI.

The damn thing still wouldn't crank over so I grabbed some starter fluid, tried cranking it and yet STILL won't friggin start -- it had 1 or 2 power strokes, but wouldn't start still.

So, I was thinking my spark plug wires were in the wrong order, or the spark plugs were flooded.

I verified the spark plug wires were in this order (please correct me if I am wrong):

34
12

And still will not start. I tried squirting a lil more starter fluid and no luck.

Then, I took the spark plug wire out, put a screw driver in the spark plug, cranked it over and I have no spark! wtf??

My friend and I took off the dist cap, and everything looks clean. So, we tried another spark plug wire, made sure we had the spark plug at a proper ground place on the radiator support, and still no spark.



I'm pissed and a lil stumped at this point. I know I can tap into the dist and start replacing things, but I find it hard to believe that I once had spark, and now I have no clicking fuel pump or spark. It HAS to be something simple

Any input would be MUCH appreciated.

I had the same problem in my hatch and it was the ground to the fuel pump.

poison

What did you do to fix the problem?

SinisterCivic

i checked all the grounds to the fuel pump and disconnected and reconnected them for some reason they werent grounded the first time around? Go figure.

fastwanabe

I would suggest you take a MM and confirm 12volt at the fuel pump plug. If the power is there confirm the pump works by applinying 12 volt from a battery or whatever. If pump turns on then check the grounds. about the no sprk deal make sure ALL the motor grounds are tight on the block(my car wouldnt start and this was why). If all checks out make sure the fuel line isnt clogged.HTH

Sounds to me that your ignitor in the dist is out. Its odd that it went out between swaps but its possible. Also i would track down every ground possible. When i put the h22 in my civic it started but then died and wouldnt start. Come to find out the ground on the starter was not connected. It ran fine after that though.

poison

thanks guys, i'ma try that. i have a couple friends comin over right now to take a look at it. It has to be something I missed while swapping.

thanks ;D
