Since this does use a fuel injection system, 2 things to check are 1. the fuel pressure. Check to see if it is bleeding down overnight and the fuel filter is plugged. If it is bleeding down, replace the fuel pump. 2. The coolant temp. sensor which senses how cold or warm the coolant is atells the computer how long to keep those injectors open to allow for cold starts. Just to be safe, have the battery tested at your local auto parts store. They will usually do this for free. Let me know what you find. What model Cadillac do you have?

The "check engine" light will "light" when there is a malfunction in the engine management system. The fault code is then stored in the computer. The computer must be scanned to retrieve these stored faults to pinpoint the malfunctioning component. Its possible that your temperature sender may be the problem.

There are a number of things that can cause your stalling problem: EGR valve hanging up, fuel pressure regulator sticking, fuel pump failing or a faulty computer, etc. With someone fault code we could send additional details.

Keep us updated.

My 2000 jimmy takes about 10 to 20 engine cranks in the morning when its cold out.when it starts its good the rest of the day. but its getting worse the amount of cranking the engine over in the morn


I'd use a fuel pressure gage, check fuel pressure, key on, engine off, first thing in the morning, 60--66 psi, spider fuel system. If you have the spider fuel stem, that system is noted for problems.
There is a service bulletin for cold start-up problems, caused by fuel poppet valves sticking. Once you get it started, it runs fine the rest of the day. The poppet cleaning procedure shows to be a shop procedure.

1997 acura 3.2TL needs lot of cranking in codl


Hows your oil level?When was the last oil change?May take more to get it started if oil is low or old.Oil turns to syrup in the cold.

Another possobilty is the cranking amps of the battery or the amount of power it will put out. A higher cranking amp battery will turn the engine more efficiently.

Check the cold start switch and there are other possibilities. You may want to have the computer checked with a code reader. This can be done for free at most auto parts stores such as checker shucks kragen or autozone and the like.
