92 dx ecu not priming fuel pump Ic17 issue?
92dx not getting fuel pump to prime, but take a hair dryer to the ecu and it runs fine...is it the c17 doohickey? If so where/what part to buy to solder new one in?

Re: 92 dx ecu not priming fuel pump Ic17 issue?
Here's a related post from the HT site https://honda-tech.com/forums/honda-...-work-3109898/
If the fuel pump relay is not the issue then you'll have to remove the ECU (disconnect battery first) and open it up to inspect the capacitors for bulging and/or leaking. The link above mentions C14 capacitor. Where did you find info that it's C17?
Notice the circuit board in the video below it has labels for capacitors (C), resistors (R), and other components by their respective number(ex: C14)
Your ECU may have developed condensation or even a leak somewhere on the body may be causing it to get wet? Inspect for bulging or leaking capacitors and if you don't see anything obvious the use a hair dryer to blow dry the ECU circuit board. Afterwards spray it with Deoxit This alone might solve the issue.
While the ECU is out use a hose to spray your car down from the top to see if there is any water intrusion near the ECU.
Take pics of the ECU board and post them here if you have any questions.
If you find any bad capacitors their uF and voltage (ex 33uF/100 volts) rating will be written on them. Do a search online to find a replacement. This might help https://www.google.com/search?q=92+9...client=gws-wiz
