this is a old model and it should have a cold start valve or it should have a coolant temp sensor, replace the colant temp sensor which is usualy located on the thermostat housing or on the intake manifold and this will sove the clod start problema!!

Check the fuel pressure, bad fuel pump or sock on the fuel pump and fuel filter check spark plugs and check distributor cap, a fuel pump is $273.00 or a bad injector $110.99 or BWD Fuel Vapor Pressure Sensor for $35.99 any of these parts could cause the problem, so without doing a fuel pressure test it is a guess, if the vapor switch is bad it could cause a long crank time if the fuel pump is bad it has a check valve in the fuel pump, if the check valve goes bad the pump can't maintain fuel pressure so on start up the fuel has to pump from the tank all the way up to the fuel rail, if the injectors is bad it could leak after engine shut down and cause you to lose fuel rail pressure. Also the fuel vapor sensor could be stuck open and could cause the problem, all need to be tested, you can rent the fuel pressure tester from AutoZone or advance auto or Shucks they return your money when you bring the tool back as long as you buy the parts to repair it from them. That would be the first thing I would check fuel pump pressure and if you replace the pump then change the fuel sock as well. That model was not meant to burn ethanol and can kill the fuel sock the fuel pump and filter.

It probably is your glow plugs which are controlled by the cold start relay. They burn out over time. This is normal. Haynes Diesel Engine Repair Manual, part 10330, will walk you through the diagnosis and replacement easily. It's about $20. Hope this helps.

on your next fuel up add 93 octane fuel and a bottle of Fuelinjecto cleaner (not Octane Booster). This did the trick on my 95 blazer
