91 accord hard to start when cold

whenever i let my 91 accord sit for more than a hour it has a hard time starting. to get it to start you have to mess with the gas pedal to get it to fire. generally speaking on these accords what are the most likely causes of this problem?

Let the key sit in the on position for several seconds (5 should be good) before trying to start the car. It gives the fuel pump time to prime/pressurize the fuel system.

You could always check/clean all your grounds, thats free.

How old are your plugs, wires, distributer cap & rotor?

Intermittent starting problems can also be caused by the pgfi main relay going bad. Over time the solder connections crack (not visible without a microsope typically). You can refurbish it, by resoldering each component/part one by one (the cheapest option), or you can purchase a new one from honda for about $40. Although main relay starting symptoms typically occur when its hot outside.

I do not think it is the messing with the gas pedal that is getting the car to start...more likely the time it takes to mess with the pedal builds gas pressure.

it could be a weakening seal in the fuel pump...someone mentioned this in another similar thread/problem, that guy had to do what was also suggested in this thread...turn the key on and sit for a second. Also wanna check the main relay like cloudasc said.

I'm also guessing it is that since it does this right after you turn the car off...one hour is not long enough to fully cool down.

If it ONLY did this when the engine was cold I would lean towards something else.

i had this issue with my turbo'd cb9. The car would take a bit to start if i just sat there and cranked it. Even if i let the pump prime till the CEL went off. But if I tried to start it with the pedal to the floor, it would start immediately. Never did figure it out but it did bug me. Good luck figuring it out cause i would LOVE to know what it was

going to try replacing the coolant temperature sensor today because i also noticed my temp gauge doesnt work and i had to pull the fuse on my coolign fan because it would keep runnin even with car off and keys out killing my battery. i heard of all of these problems relating to the ect sensor and its only a 25 dollar part so worth a try.
