Have you tried changing the fuel pump relay under the hood? it may be old, and the cold could be having an effect on it.

i can walk you thru all fueling issues of any car.
why not post whats up;?
btw fueling is cut on all EFI if the EFI detects lost spark
so we check that 1st !

Fueling , EFI , is complex, (kinda) but is simple
the EFI dont fuel the engine, if there is no spark
or if it thinks you crashed, its a built in protection.

some cars inject and then stall in 2 seconds, due to , no spark.
the ECU monitors spark if it sees it drop dead, fuel ends.
even if spark is good. see why (answer, its a monitor)
the monitor works different on all EFI made.
fixed many.

I have a 1987 ranger 2.3 EFI and sometimes it will not start when it's cold. after it warms up outside it starts. When it does start it runs great. It always starts when warm. some times it will


Timing belt being off one tooth will not cause this problem but rather loss of power and hard starting all the time,

in the cold it will not start, the engine will spin but wont fire is this correct?

There are many things that can cause this, a little testing will be needed, the first thing that comes to mind with the ford and cold weather is the coolant temp sensor, it give computer a false reading and can cause hard starting or even no start, a scan tool would be helpful to see what temp it is give computer.
The best way to narrow this down to to check for spark when it wont start, a weak coil in cold weather will cause this problem or bad coil wire to cap, but if you can see if it has spark and let me know,
another test is to check fuel pressure, to see if it is getting fuel, and the fuelpump relay,

Let me know if it has spark or fuel when is does not start, good day

1984 toyota pickup 22re fuel injection is not getting fuel to the cylinders


Most likely a fuel pump problem, locate the diagnostic check connector under the hood and turn the key on then put a jumper wire between the terminals FP and B+ if it start then the fuel pump is ok and the problem may be the EFI relay or efi fuse

Fuel pump most likely the problem. check both relays EFI AND CIR OPN tested both by adding power to the pickup coil and with a meter accross the normally open contacts they all worked fine, I also...


if the car doesn't start then the camshaft error can be a probable cause. but to check power to the fuel pump just probe the wires with a test light one at a time. the one that powers the fuel pump will turn the light on for 2 seconds and then go out . the computer does this until it sees a cranking signal then turns the pump on to allow the car to run.

My 1991 toyota 4runner keeps blowing the efi fuse and my engine floods gas. what could be the problem?


Check the EFI main relay, the circuit opening relay, and the fuel pump relay. Inside the fuel pump relay there is a switch controlled by a coil. During start, the fuel pump gets full power for a couple of seconds to build up pressure. Once pressure is good, the fuel pump relay is supposed to switch (via the coil) the fuel pump to reduced power. If the coil in the relay is bad, the reduced power setting is not available and the fuel pump will run at full power all the time. At this heavy current draw, it won't be long until the EFI fuse blows. This would also give more pressure than is necessary to the cold start fuel injector which runs on a timer. This extra pressure during the time that the cold start injector is operating may be the reason the engine is flooding with fuel.
