Fuel pump relay, maybe
Remove the ingnition mudule located on the driver's side fender, no on top of the fender skirt, on the fender near the firewall. I think it's a 10mm. It looks like a black box(1 1/2" x 4") mounted in an aluminum heat finned casing. OR it is attached to the bottom of your distributor 9(same physical description minus the aluminum piece). Now that you've found it and taken it off, take it to your local autozone and have tested at least 8 times in order to heat it up to normal operating temp. If it fails, BINGO! You answered the million dollar question that plagues and drives Ford owners insane trying to figure it out. You see, this module when it decides to comletely fail will stop your truck from firing and will stop your fuel pumps from pumping, leaving you dead. NO spark, No fuel.
CHECK YOUR RELAYS.......POWER AND FUEL PUMP RELAYS, ONE OR THE OTHER
CAN OPEN WHEN HOT RESULTING IN FUEL PUMP SHUTDOWN:
Grounding issue, bad wiring, failing bulb.
The sun warms the earth.
timing delay sensor
coolant temp sensor not working
that would be the automatic choke working until engine warms up enuff not to need a choke
It's probably the ECM or Electronic Control Module which sits right behind the distributor cap. These have a history of getting hot and not working properly when they get old. Autozone tests them for free.
A faulty temp sensor.
the oil pressure in the engine rises when the truck is warming up causing the light to show, if continues after the truck has been running, change oil and oil pump.
Your body warms up because your heart rate goes up adn your heart pumps more blood and more blood faster.
The computers in the 1990-1995 have bad capacitors and they can cause a no start. Every easy to fix though. Check out Suzuki Forums. com On_mitch
It will get pushed out onto the ground as the engine warms up.
