1993 Cadillac eldorado drove to work fine when tried to go home it wont start no service engine light on no codes to pull?
I would suspect your fuel pump. This can fail without warning
and on the older obdI vehicle rarely had codes for it. Crank it a
couple time and then pull out a spark plug and see if there is fuel
on the tip. If not I would replace the fuel pump relay. I dont know
which one it is, but it will be located in the distribution box in
the engine comprtment. Maybe you will get lucky and this is all
that is wrong with it. Also it elimenates the possibility of bad
relay. Also make sure you are getting spark. This should be the
first thing you should check, actually. Use an inline tester or
take a plug out and touch it to the block (plug wire attached) and
crank the engine and see if it sparks. Be careful though it packs a
punch if touch the plug. If no spark then the coil pack or
something like that is malfunctioning. Well, gives you a place to
start. Good luck.
also you may want to try having your electronic ignition module
tested its under the rotor button in the distributor be careful tho
when you remove it the wires can sometimes be extremely brittle my
car did the same thing and this fixed it by replacing it also try
your ignition coil which is on top of your distributor cap these
things can go bad and will let your car crank but not fire and
their relatively cheap to replace given you have the 4.9 not the
north star. around 20.00 for each which isn't to bad.
