Idk if there is already a post about this but if there is I obviously didn’t look hard enough. I just dropped a b20vtec into my car and I’m now having a crank no start, I was getting no spark so I went ahead and just got a new coil, rotar, dizzy cap, wires for a b16 an Ngk iridium Plugs still no spark. I also have a chipped ecu specifically for my b20vtec car gets fuel I can hear turn on but my check engine light doesn’t go away stays on until I try an crank it. I checked my fuses none are blown I have ground on thermostat ground from tranny to chassis an block to chassis I’ve been at this for 3 weeks now an I’m still just getting crank no start.

 

Ecu plugged in is stock p72 an the other is chipped one tried both but still just cranks.

 

What fuel line did you use between the fuel filter and fuel rail ?

 

Idk I’m using the one that came on the motor when I picked it up

 

If the top picture is currently what it looks like, your crank sensor is unplugged and you have atleast 3 vacuum leaks

 

alright I’ll install all my vacuum hoses an are you talking about the plug Sitting on top of my windshield I thought ob1 ecu did not have that sensor?

 

How about a close up picture of that distributor jumper harness ? I see what appears to be a black/yellow wire going to nothing... and that is a 12v power wire.

 

 

I swapped those dizzy wire around and turns out I had pin 9 speed sensor hooked up to ign so I swapped pin 9 with pin 10 ign to make ign on the jumper now dizzy getting spark but still just cranks.

 

Fried ecu?? Hope not....

 

Could it be the jumper? I got the obd2 to obd1 for 96 ex coupe.

 

Could it be my car is auto an I’m using an auto wiring harness?

 

It kind of looks like the Map plug and TPS plug is backwards or the wrong plug on the Map sensor!

The map and TPS both branch off the harness with a short tail to the plug, its why they sometimes get switched around when doing swaps.

I'm pretty sure the plug you have on the Map sensor is wrong! It has a long lead to the plug which does not look like the Map sensor plug for a B series Vtec harness.

Verify you have the correct plugs the Map and TPS sensor.

 

Alright I’ll do that rn I’m just gonna go through every plug again. An on another note with my cel light if that constantly stays on that doesn’t necessarily mean I got a fried ecu?

 

Cant say but I'm 99.9% sure you have the wrong map plug on and that's why it wont start! Looks like you put the O2 sensor plug on the Map sensor and Map plug on the TPS sensor!..

 

no other plugs able to plug into the tps or map just these three an one of them I don’t have that plug type.

 

Your last photo shows you holding the 3-wire IACV plug... which means that you do NOT have the IACV plugged in correctly. You must convert this plug to a grey two-wire plug and modify your wiring inside the passenger compartment at the ECU plugs. Why did you use an automatic engine harness in a manual chassis ?

 

Man you all need to stop and pay attention to what's going on. The guy is clueless and doesn't even realize he's got a cable trans in an ek chassis. He needs someone to do this for him, not tell him it could be this or that, not sure.

 

Lol

 

God damn everything I’m using came with my shell an I’m using hasport cable to hydro conversion kit so yeah I’m using cable trans only cause no kne has a hydro trans I’m using what I got an ima keep doing it if you ain’t helping that’s cool but either way I’m gonna keep going an get this done thank you for letting me know I gotta concert all my plugs I’m gonna take my harness out an complete this.

 

Want me to convert to this is there any forums using auto harness converted to automatic?

 

 

These the other two harness I have
But they are missing plugs

 

Swapped it I discarded the orange wire that was in the three plug pin an used the black yellow an blue an black wire.

 

What engine harness are you even using?
