Gp Enigizer Question
Ok When My Truck Sits Over Night Or For A Few Hours I Half To Cycle The Key About Ten Times To Start My Truck Is This Coused By The Enigizer And If So Is It The Solinoid .is It The Same As The Starter Solinoid If I Need To Replace It
Also What Would Be The Best Glow Plugs To Use In My 93 7.3 With A Banks. And How Will I Know If I Need Them
And Last When I Start The Truck I Get Alot Of Blue Smoke From The Tail Pipe And From The Turbo Is This Coused By The Injectors Or What .if My Ac Is On You Can Smell It ...as You Can See Im New To The Desil So All Help Is Appreciated

I assume your asking about the 93 since you list a different truck in your profile. Required cycling of the key may be an indication of bad GPs or a bad controller ground.
Beru/Motorcraft are the best GPs...... IH/Navistar has... IH 1819649C1... SSDD.

If you have 2 or more bad GPs, the controller may not cycle at all.
Two problems that occur with the solid state ( 1987 to 1994 IDI engines ) GP systems. If a GP burns out ( circuit resistance goes up ), the controller cycles the GPs at a faster rate which doesn't let them get to max operating temp. If 2 or more GPs fail, the controller may not cycle the GPs at all ( very rapid or no clicking heard ). When you check the GPs, use an ohmmeter. A high resistance ( not necessarily burned out ) GP can cause circuit resistance to go up and the controller will then cycle the GPs too fast. You probably will not find this problem with a test light. Resistance spec for GPs = .5 to 1 ohm cold. Second problem. A poor controller ground ( black wire attached to valve cover stud ) will cause the controller to leave the GPs on longer, often damaging or failing them. If you are having mulitple GP failures, I would check closely the controller ground. Now the confusing part. Bad ground --> longer GP on time ( slower cycling ). Burned out GPs --> faster cycling If you have both situations, it may appear that the controller is cycling the GPs at the proper rate. Bad ground slows it up while the burned GPs speed it up ---> normal cycling. The system acts/sounds like it's working normally, but you have a hard starting concern.

Glow plug torque is 12 ft lbs, I always use antisieze on the threads.

Whats it smell like with the AC on? Excaust or fule? If it smells like exaust you have an exaust leak some where pluss you said you have smoke coming from the turbo. If its fule your return lines or return caps are leaking If so it would be a good idea to pull the injectors and have them pop tested while replaceing the return lines, caps and orings.
