93 Civic EX 1.6L in Storage 4 Years Now Fuel Pump not Priming
Had car in storage and never started it during the 4 year storage period. I'm not getting any fuel to fuel filter. I removed back seat and fuel pump cover and when cranking engine, I'm not getting any noise from fuel pump. It isn't priming or even clicking on. Is it common for fuel pump to go bad in this situation??
Check fuse 31 and 24 and resolder the main relay.
Also clean and tighten the G101 ground wire attached to the thermostat housing.

I was thinking the fuel may have gummed up and damaged the fuel pump originally. I will check the fuses and let you know. Is this a common problem with cars in this situation??
Hi Ron,
Thanks for your help with this repair. The CEL light does not illuminate at all when turned from off to on(II). It does not illuminate for even 1 second. I also put voltmeter on fuses 24 and 31 and they both get battery voltage on both sides of fuse with ignition switch set to ON(II). Engine still only cranks and no fuel to fuel filter in engine compartment and I don't hear fuel pump working. What should i check next? Thank again!

Again, also clean and tighten the G101 ground and resolder the main relay.

This is weird to me but I don't believe I have a check engine light in this cluster. I've looked all over. Where would the check engine light tab be? I searched the board and found another thread where somebody had a cluster also without CEL. I may have the exact same cluster. In the thread there were some pics posted so when I have a chance I'm going to compare to see if that is the same cluster I have without CEL. If this is in fact true, no CEL in cluster what would the next step be? Thanks in advance for your help with this problem.
You almost surely have a CEL indicator in your cluster. Remove the cluster and check the CEL bulb. Is it missing? Is it burned out? In either case, you can temporarily move a known-good bulb to the CEL socket.
I have some more info here. I have located the check engine light tab. It was located under fuel gauge in a small cluster of tabs that I missed. I also cleaned/sanded the G101 ground connection at the thermostat housing. It didn't look corroded however I got it shinier. I also jumped terminals 1 and 7 in the main relay connector with a paperclip and got some sparking however no noise from the fuel pump. Not sure what to do next?? Thanks again for all your help in this thread!!
I have some other advise for you, not related to your question.......
Since the car has been parked 4 years, i would do two things:
- change the timing belt before driving it around very much
- drain any old fuel before using the car
Trust me on both of these

What happened when you jumped 5 to 7, as I mentioned earlier?
I just noticed that the check engine light now does go on for a few seconds when ignition switched to ON(II) and then goes out with a clicking noise from main relay. I double checked fuse 31 and it gets battery voltage to both test tabs at top of fuse. When I jump terminals 1 to 7 and 5 to 7 of main relay I get sparking and paper clip wire gets hot. Still no noise throughout all this from fuel pump.
I still haven't done any soldering in main relay. That may take a little time for me to figure out since I don't really have any experience in soldering.
What is the easiest way to drain out old fuel in tank??

I also just tested for voltage at the fuel pump connector. When I turn ignition to ON(II) I get battery voltage at fuel pump connector for about 2 seconds then it drops to zero. Does this mean fuel pump is defective?? What do I need to do next to confirm defective part? thanks again in advance for all help.
you should drain the tank by using one of those pumps they sell at home depot that could b used with a power drill or u could raise the back of the car real high while u crank it lol and bang on the fuel tank while cranking just some back yard tech advise lol

When I performed voltage test I used both terminals on the fuel pump connector. I put the + probe into the power terminal side of connector and negative multimeter probe into ground terminal of the connector. I didn't use car chassis as ground. Does this confirm it is the fuel pump? Thanks again for all the help on this Ron. Do you also believe it is important to drain old gas from tank before running the car?

Yes, if you have a lot of old gas in the tank, then drain it.
I also just noticed now that when turning the ignition switch from off to ON(II), the CEL does not come on for even a second once again. I checked fuse 31 again in engine compartment and still gets battery voltage at both test tabs still. What does this mean with the CEL not working, then the light coming on for a couple seconds earlier today and now not working again? Thanks again.
if you didnt keep the gas tank full when storing the car, the pump seals/bearings whatever dry out and it probably seized the second it began rotating
Yes the oil light stays on. The CEL was working correctly earlier today but now back to not lighting up at all when turned to ON(II)
