'93 occasional hard start
Hey guys. I've finally gotten around to addressing my hard start problem. It happens randomly. When its warmed up, and when it cold.
What it does: sometimes it cranks over instantly, other times it takes it a few seconds.
I just put in a brand new, charged, battery yesterday. Didn't help anything. Based on my research, I think it might be the coil, or ICM. I'm really hoping its not the opti, I really don't want to rip the whole front of the car off.
Can someone confirm this, or was having similar problems and know a fix? Thanks in advance.

From my experience icm, and coils normally work or don't work (with the excepting of a few ford icms).
I would look at the fuel pump relay.
My old Camaro would do this and I did not figure it out until after I wrecked it and the wiring harness with the fuel pump relay was installed into a different car. In the new car the fuel pump would not turn on via the relay and I found a faulty wire connecting it.

I am not sure if the relay is located in the same place on a 93 as it is in a 97, but on the 97 it is on the drivers side under the kick panel.

The coil can defiantly work just enough to start the car and cause all sorts of drivability issues..

The connections to the coil are a bit dusty (DD probs) When I get home tonight, itll try to clean them up with some of that electrical connection cleaner in a can

I would think if the coil were the problem it would be something other then hard starting.
Can you explain for future readers (form searches).

If the car is getting weak spark it can either be hard to start or not start at all.. But it will also feel sluggish under load..

When my coil went bad it would turn over a really long time before starting if it was bone cold. If I had driven the car in the past 5-6 hours it would start up right away, but letting it sit overnight always made it hard to start, regardless of the temp outside. It always ran fine once it started tho. Took a month to figure it out and over that time the cold cranking kept getting longer and longer!
