Cool 1988 Sammi won't start!!

My 1988 (early) Suzuki Sammi has 150,000 miles and indicates good pressure in each cylinder. It is cranking merrily, but will not start. It has new plugs and wires, new alternator, new starter, new battery, new ignition coil, new fuel pump and filter. When I pour gas in carb, it fires immediately but will not start and run.

Is it the carb (original) or in-dash computer box, or ......?
Any help is appreciated.

Fact that is does fire up when gas is poured in would lead me to believe its a fuel delivery problem. Did you pull, check and replace the fuse to the fuel pump?

No Gas

Sounds like you have a bad fuel pump. Remove the hose from the Fuel pump that goes to the carb and direct it into a container that is OK for gasoline. Crank engine while observing if there is any output from the fuel pump. Fi there is fuel coming out then your carb is not working and needs to be cleaned/repaired. If there is no fuel from the pump Remove the two nuts that hold the pump,12mm socket, and work the pump manually by pushing on the lever. If you get no fuel, replace pump. If you get fuel then the pushrod or the cam lobe is bad. The pushrod for the fuel pump should measure 2.145 inches. The stroke of the pushrod is about 1/6 inch so you should be able to activate it manually. You need fuelin the bowl of the carb to run. Hope this helps. Keep us posted.

Fuel Pump Fuse??? Put on your thinking cap...


LeeClark:
Some of the more curious problems that the '88 Samurai is prone to is

1. Vacuum leaks (lots of hoses everywhere on the Hitachi Carb).

2. Bad ignitor - an electrical gadget inside the distributor

3. Easily-damaged mechanical fuel pump.

and...

4. Clogged up fuel filter.

Since you get a spark and it runs with direct injection of fuel, #2 can be eliminated.

You said that the fuel pump is new. Assuming that you did not accidently perforate the pump's diaphraghm installing it (It can be done - I did it once...) we can eliminate #3. That pesky fuel pump fuse can be eliminated too!

That leaves vacuum leaks and a stopped up fuel filter.

If you disconnect the inlet hose to the carburetor from the fuel pump and crank it over a bunch, you should get a good stream of gasoline to pour out.

If the fuel pump is busted, the pipe on the side of the fuel pump that does not have a hose on it will be bleeding gasoline (or possibly oil).

If nothing comes out of the fuel line, you have a clog - most likely in the fuel filter.

My guess is that the fuel filter is clogged. It is located inside the passenger rear wheel well on the inside of the frame. Replacing it is not a diffcult task.

Vacuum leaks have to be pretty serious to make the engine not run at all. Nonetheless, you might want to check them out anyway just to be safe. For detailed info on the carb's vacuum system, try a search for vacuum at Ack's FAQ - the link is in my signature.

I hope that this helps!

LOL! Silly me, I forget, not every Samurai is EFI!

My thinking cap? Well, its fogged by the following:

10 mg Hydrocodone 2x daily
10 mg Cyclobenzaprine 3x daily
20 mg Oxycodone 1x daily (night)

More like I'm wearing a jester's hat than a thinking cap.
