Have a spoon chipped p72 ecu bought off ebay that codes a 21 vtec solinoid. Pulled it out and put a buddys stock b16a (p30 I think) in it and its fine. Checked the wire and its fine to the ecu. Jumped 12v to the solinoid and it clicked. Is the soliniod wire on the p72 in the same A4 slot as any...

Thanks to all who helped with the last one here we go again. Got the o2 wired and cleared the ecu and now I have a code 21 vtec solinoid.The wire I ran to the ecu is good (ohms out and no shorts) and is in the A4 slot. The solinoid clicks when I throw 12v to it so why am I coding? Will this swap...

Needed injectors after installing the right size the code left. Thanks to all.

...bosch) used the original wire for sensor input(d14 Black on bosch) and run a wire for heater control (A6 White on bosch ). Now the car will run again but still code #1 )(&(*&)(^*( ####. This is a brand new bocsh universal. A buddy used one in his and it worked fine. What is the deal???? :mad:

Ok so d22 and a25 are power and ground for all (or most) sensors so i just splice in for both. The sensor input is the one wire I orginally had. The A6 (or heater controll) is the only one in the harness that just dead ends so wire up to it and let her rip then???

run the wires from the o2 to the ecu. Now when I looked at the chart to see where to plug in o2 sensor ground D22,12v power A25, and heater control A6 there are already wires in the plug. Was this car even thougth its a one wire still wired at the ecu for the four wire system? Should I just...

Thanks

Hey, How can I check the fuel pump on my 1989 crx dx. Its not running when the switch is on but I have no head lights either. Are the two problems related? where can I check for juice to the pump short of pulling out the tank? Also where is the head light relay. Thanks

New twist. Put the injectors out of the d in the b and now it cranks and runs ok. But the car is a cx (the cheepest thing on the planet right?? no radio or antenna, air or luxury of any kind) I seen in a post that the cx injectors in a d are only 180cc. that is small enough to fry the b right...

b18c1 out of 1997 teg in a 1992 hatch. What type injectors should I have? It has 330cc venom's in it. When its cold it don't take nothing to flood it. The gsr was obd2 orginal but now is obd1 in the hatch. Will the injectors out of the d work in the b? or are they to small cc?

u da man thanks

Does the vtec oil presure sensor in some b18c1's go in the back of the head and in the solinod of others. I have a hole in the head next to the dizzy pumping oil but my sensor is in the solinod. Do I need to plug the one in the back of the head.

Putting a b18c1 in a 92 hatch. A new engine thats not been run yet. The injectors (Guy told me they were aftermarket) that are on it had notchs that would not line up with my harness. Filed the notchs off so they would fit but now it floods when I try to crank it. The spark appears weak. Can't...

dumb question but how or where do I get it chiped in va.

Didn't want to here that just got the p72

Hey, Putting a b18c1 in a 92 hatch. I have a edelbrock jg intake and trying to wire car vtec according to the diagram. I need to wire the car for secondary intake sensor but with this intake it isn't there is it? If its not wired will vtec work and not throw codes. Thanks :blink:

When I took the sensor(one wire 1992 cx) out of the manifold it screwed the threads. A new one is $273. 00 at advance. I have a four wire (1997 gsr). Can it be used obd1. Like to save the cash.

Anyone have a diagram on how all the coolant hoses run on a b18c1 in a 1993 hatch. I have a picture to email to show what I need just contact me. Thanks

The transmission in the hatch is shot (grinding and such). I know the casting will not work because of mounting and hydro vs cable, but will the internals out of the crx trans work in the hatch's casting.

I have a 1988 crx dx and a b18c . I put a b18a into a 1989 crx si about a year ago and it was plug and play. This one needs more though. The engine is a b18c1. It has been bored .020 with eagle crank and rods, J&E 10.5/1 pistons still has stock cams with eldelbrock 4760 intake. It was built to...
