I just did a b18c1 swap in my 99 ex im running a p72 ecu with the immobilizer removed. after repining the fuel pump relay from a16 to a 15 and also doing the crank sensor trick i finished everything i go to turn it over and have no fuel and no spark. before i get really pissed and buy hondata and find out that doesn't work either is there anything im overlooking or haven't done???????? what could i have possibly screwed up please help im desperate at this point

 

Did you check fuse 44 and 13?

Is the G101 ground wire attached the thermostat housing clean and tight?

 

I did check the fuses they are good i didn't check the ground yet once i get back to the shop tonight ill check it. There has to be something stupid and so obvious that i missed every plug is plugged every pin i needed to repin has been. Ive spent hours to make sure everything was perfect and i cant figure this **** out.

 

anyone else wanna chime in??? help me think of things i could have missed that would cause no spark or fuel the pump don't prime or anything

 

ok i checked the ground its perfect and i cleaned it extra good. both fuses are good. im stuck i dont know what to do please help!!!!!!!!!!!!!!!!!!!!!

 

Now use a multimeter to test whether the main relay plug gets voltage from both of those fuses. Also check the main relay itself.

 

ive got no power to the main relay and no power to #13 fuse for the fuel pump

 

damn 90 views and noone else has ever had this same problem?

 

i give up for tonight im phuked

 

Fuse 13 sends voltage to the main relay on a Yel/Grn wire that pins to terminal 5 in the main relay connector. Or did you measure no voltage at the Yel/Grn wire that pins to terminal 4 (fuel pump) of the main relay connector?

 

I got no juice to the fuse itself i took the fuse out and checked the terminals in the fuse box and nothing also any suggestions???

 

Did you have the key in ON(II)?

 

im honestly not positive ill me at the shop in a half hour ill check everything again

 

Fuse 13 gets power via the ignition switch. If it's off, fuse 13 obviously will not have battery voltage.

By contrast, fuse 44 gets voltage from the hood fuse box so is hot at all times.

 

i figured out what was causing no spark or fuel when i did the crank sensor trick i cut the wires in the wrong spark you must cut them before the splice not after. So huge screw up on me and also the fuel pump wire was not pushed in all the way so fixed that to. thank you for the help, but now i have another problem with my stock ecu it fired up but only for seconds, with my gsr ecu my cylinders filled up with fuel so what could that be now do i have to pull my splicing apart and check all that? it ran good with the stock ecu but only for seconds, with the gsr it did nothing
