Author Topic: starting issues after installing a na pump on eco td (Read 2709 times)

I installed a na pump on my 92 eco which is in a suzuki samurai. Now it runs great and has more power than before but I cant get it to start in the morning, the glowplugs are new and working, it cranks fine but it puts out alot of dark grey smoke but will not fire. After the ambiant temps come up it will crank and fore fine. I did time it within factory specs, with cold start toward the pully and put it away from the pully for starting/driving. It almost seeme like when a gas engine floods and you have to crank with out touching the accelerator. If I do it cranks slower and takes more cranking and more dark smoke before it wants to start. could this happen from dirty of clogged injectors?

What do you have the engine timed to?

Is the engine cranking over at a nice quick speed?

Once it starts and runs for about 30 seconds can you turn it off and will it start right back up?

timing is at .035in. engine is cranking properly. once it starts it will run and start for the rest of the day. I get alot of smoke during and, zoero to hard cold starting.

Some thoughts:

- you can certainly advance the timing a bit more... 0.039" is not unreasonable

- for sure you had the cold start knob pushed all the way in when you did the timing ?? Real common oops....

- could be nozzles, could also be that your compression when cold is poor. Nozzles can be poptested, and a cold compression test might tell you something as well

Will the na injectors work as well as the eco injectors?

sounds like you have an air leak somewhere in the system. how did you bleed out the system?

why don't you do a simple test; in the morning put a vacuum pump (if you have one) on the out of the pump. turn the key to the ON position (to open the stop solenoid) and then pull a vacuum to suck fuel through. pull a reasonable amount of fuel through to make sure that any air has a chance to escape. after that hook it all back up and fire it up. if she starts fine, then obviously it has to do with fuel. at least if you know that is the problem, you don't need to worry about injectors, etc. if that doesn't solve your problem, it could still be the injector return lines. after I replaced the main line going to the pump, the car took around 1 minute or so of cranking just to get the fuel going through. the engine would not start! (it huffed a little bit, but seemed 'lifeless')

let's hope that it's something simple!

I will try that in the morning.

The only potential problem I see with jtanguay's suggestion is that you will be double cycling the glow plugs. Depending on how long it takes you to hook the vacuum up and whatnot it may not have any effect.

My plugs are set on a manual 60 amp switch

Are you using the glow plugs when you are attempting to start?

Burn, he said "the glowplugs are new and working" in his first post.

That doesn't mean he is using them though

true dat

Do you mean am I using the plugs while cranking or before cranking. I am using them for 7 seconds before cranking. On cold mornings I heat them for 7 seconds then wait 5 seconds then heat them for another 7. I advanced the timing and used a vacuum and got a good amount of air out of the fuel return and it started right up thanks for all of your help.

But now I have another problem I think it might be a blown head gasket. After I got it going I took it out on the road and it was running great but I think that I had the fuel screw in to far because there was alot of black smoke and it was obviously faster than before. While I was driving it the line for my manual boost controller fell against the exhaust and melted while under load the boost went way over 15psi. I say over 15 psi because the guage that I have only goes to 15 but the needle went way beyond probably to 20psi+ based on on needle postion. now I cant get boost over 7-8psi and it is smoking oil at idle from the exhaust. I thought that the turbo might be leaking oil so I pulled the turbo/intake hose off and it was still smoking white/blue smoke. Does this sound like head gasket to you?
