Can a auto speed control stop truck from cranking? I have a 2.0 1988 ranger

Stumped... Cleaned carb and drained tank

Auto speed control? Not sure what you mean.

Either way - no, won't stop it from cranking. What exactly happens when you try?

I get it to crank for just a second while putting gas in the carburetor but it immediately dies. In the idle speed control module on the fender well looks like it's melted so I'm going to get a new one

Idle* speed control

Clarification of terms:
Cranking is the starter's electric motor spinning the engine using the battery.
From your last post, it sounds like you're saying that it -does- crank just fine, but that it'll then fire for a moment and die?

You're right sorry about that.

And this started after you cleaned the carb and drained the tank? Or did you do those things in an attempt to fix the problem?

I did it to try to fix the problem. It hasn't been ran in about

a year

Assuming it will run fine if you manually provide fuel or starting fluid, then you definitely have an issue related to the carburetion system. Is the choke working properly? Can you manually hold the throttle partially open and try to start it?

I'm pretty sure the choke is not working. But it always crank regardless. I don't know I'm thinking maybe fuel pump?

If its sat for a year you pry got a stuck float in the carburator.

Not super familar with the carb on a 2.0 but there should be a top cover held on by a few screws, pull that off and check needle/seat/float operation.

Disconnect the fuel line and crank the engine. Does fuel shoot out? If it does then your carb is just stuck. Old gas sitting in it for a year will do that... spraying some cleaner at it wont be enough to fix.

I will try both thank both of y'all for applying I really appreciate it.

I disconnected the fuel line at the carb and not a drop when I cranked it several times. I'm assuming fuel pump? I just put a new one on maybe 2 years ago. Could it sitting for about 6 months affect it?

I'm not up on the 2.0. Is it a mechanical fuel pump? If so they only run like 5psi I think and it's a diaphragm that can deteriorate. If it sat with gas in it (especially e10) it can eat through the diaphragm. I've replaced a ton of mechanical pumps on my mustang because of ethanol. So yes... it could be dead from sitting.

Modern ethanol fuel destroys old carb systems. Eats the gaskets, seals, rubber, diaphragms etc. Its like pouring acid into them... leave that crap sit, and nothing will work. Not opinion, fact.
