Gsrtyperteg

Ok so I have a problem with my 97 gsr teg. It's running on 3 cyls. Here is what I have done to get where I am and need help. I have pulled #1 #2 #3 #4 plug wires all have spark so I proceed to check again and #4 has spark as well so I checked injectors same 123 are spraying but num 4 isn't i tried switching injectors around and problem stays at num 4 not spraying. I have pulled engine harness and checked all wires no shorts. I changed my hondata ecu to 3 different others and same problem any help figuring this out would be appreciated

I did pull fuel rail and zip tied injectors to it cranked to see if spraying and 123 sprayed 4 not spraying so I switched all injectors around again and same problem stays at number 4

What are the check engine light codes?
(if it's throwing any)

Compression test results?
Leakdown test results?

Does your car have a fuel injector resistor pack?
(if so, check the Ohm measurements for each injector.)

Use electrical contact cleaner on the #4 injector connection.

The ECU might be able to detect whether or not a cylinder is producing power.
No power produced may cause the ECU to cut off fuel to the affected cylinder.

take care,
ChrisS

Considering the money you'll spend, just buy new plugs wires cap and rotor. After that its your distributor. Use NGK copper plugs.
