Weird start up problem.

[bsr2002]

When I started my van this morning it had a very high idle, like someone flooring the gas pedal.
I turned the key off and it was still running, but it was slow and stuttering. I waited a few minutes to see if it would turn itself off, nope!
I had to remove the batterry cable.
I waited a couple of minutes and put the cable back on and it started normally. This is the second time this has happened. Any ideas?

Do you have a remote start in your van?

 

[bsr2002]

I don't know what that is So I'm thinkin that I don't.

A remote start system starts the vehicle when you press a button on the remote. It will run for a few minutes until the key is inserted into the ignition.

No remote start system

Did you see the lights, and gauges on the dashboard turn off when you shut the van down? If not, then there is a short in the ignition switch or in the wiring.

While I am thinking about it, I was having a starting problem earlier in the week just getting clicks, so I changed out the starter solenoid located on the fire wall. So this other problem started the day after I put in that part. Maybe a bad solenoid?

I'm at work right now but I will check the dash lights next time I start it up.

 

[bsr2002]

Yes, the guages turn off.

 

[BrooklynBay]

Did you install the new solenoid the same way as the old solenoid or was the wiring modified?

 

[bsr2002]

I'm pretty sure I kept the wiring the same...

 

[bsr2002]

It turned out being the new $23 starter solenoid. I replaced it with an $11 one from AZ. , been starting up fine ever since.

Thanks for the update!

I have a 1995 Aerostar 4.0 AWD/4WD. I have a" REAL PROBLEM"with starting. When I turn the key on I first hear the pump in the tank, and then the booster in the engine compartment.
Then I try to start vehicle - won't start until I have repeated the foregoing and pumped the fuel feed a few times. If it starts sometimes it acts like its flooded - and by slightly depressing the pedal - it clears-out and runs as though it didn't have a problem in the World. Now it is real bad. I won't have a batery or starter at this pace. PLEASE, SOMEONE HELP,HELP,HELP.

Desperate

Welcome to this forum! Clean the MAF sensor & IAC solenoid.

Allow your ECM to do what it does


Warren S,
I agree with Brooklyn Bay, & I would like very much to add the following.
I do not want to hijack this thread. I agree with MAFS & IAC error response you already have been given. I will contribute more to this post by adding that by pumping "fuel feed" I surmise you mean accelerator pedal. If you are doing that I'd hate to read your ECM with a scanner.

First accelerator does nor squirt or supply fuel, it supplies a signal from TPS & opens Intake Venturi plate to Air Flow thru MAFS (Mass Air Flow Sensor) But has no/zero bearing on delivering liquid fuel. Injectors do that in accord with signals your ECM gets & sends. . . .

If Key is "ON" & Engine is Not Running, TPS still Sends a signal to ECM. But ECM recognizes you are KO-EO not KO-ER [Key On-Engine Off opposed to Key On - Engine Running] so ECM's at a total loss as to how to respond to a demand signal + it's inability to respond, since it knows your engine is not running. Then you stop cranking & restart the sequence again, and again and again until it starts. Confusing? Imagine what it does to Logic in OBD1 PROM Chip.

Once you get your MAFS / IAC problems corrected, try this. Enter Vehicle, turn key to on position, wait 'til your Piezo beeps 5 times & quits, +/- 3 seconds elapse time, then crank engine without touching your Accelerator pedal. Let the OBD-1 ECM do what it must do and it will probobaly start up right & cold idle as it warms it will lower idle speed according to programing in your ECM's PROM chip. When it all settles down you're good to go & should be for 100,000's of miles if you continue this regimin.

Cranking your starter while piezo sounds is a sure way to put variable volts & amperage through your ECM while it's attempting to Initialize, Load Run and operate your engine as programmed.

When you fire up a PC or Laptop before it does anything it must first initilize itself. Well so does System in your Aerostar, or any vehicle with OBD-I OR OBD II operating systems. Doing this and not trying to second guess or add old school remedies to new tech system with new tech issues will insure you a better, longer, more trouble free relationship with your vehicle. I will say if you are truly "into it" learn how Digital Control capability of an ECM actually works. It's not that complex I assure you.

CIAO & Many happy trouble free miles in your 95 Aero.
